+
+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement over email at
+coc@koesters.xyz or over Matrix at @timo:conduit.rs.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.
+

-# Deploying Conduit
-
-## Getting help
-
-If you run into any problems while setting up Conduit, write an email to `timo@koesters.xyz`, ask us in `#conduit:matrix.org` or [open an issue on GitLab](https://gitlab.com/famedly/conduit/-/issues/new).
-
-## Installing Conduit
-
-You may simply download the binary that fits your machine. Run `uname -m` to see
-what you need. Now copy the right url:
-- x84_64: `https://conduit.rs/master/x86_64/conduit-bin`
-- armv7: `https://conduit.rs/master/armv7/conduit-bin`
-- armv8: `https://conduit.rs/master/armv8/conduit-bin`
-- arm: `https://conduit.rs/master/arm/conduit-bin`
-
-```bash
-$ sudo wget -O /usr/local/bin/matrix-conduit <url>
-$ sudo chmod +x /usr/local/bin/matrix-conduit
-```
-
-Alternatively, you may compile the binary yourself using
-```bash
-$ cargo build --release
-```
-Note that this currently requires Rust 1.50.
-
-If you want to cross compile Conduit to another architecture, read the [Cross-Compile Guide](CROSS_COMPILE.md).
-
-## Adding a Conduit user
-
-While Conduit can run as any user it is usually better to use dedicated users for different services.
-This also allows you to make sure that the file permissions are correctly set up.
-
-In Debian you can use this command to create a Conduit user:
-
-```
-sudo adduser --system conduit --no-create-home
-```
-
-## Setting up a systemd service
-
-Now we'll set up a systemd service for Conduit, so it's easy to start/stop
-Conduit and set it to autostart when your server reboots. Simply paste the
-default systemd service you can find below into
-`/etc/systemd/system/conduit.service`.
-
-```systemd
-[Unit]
-Description=Conduit Matrix Server
-After=network.target
-
-[Service]
-Environment="CONDUIT_CONFIG=/etc/matrix-conduit/conduit.toml"
-User=conduit
-Group=nogroup
-Restart=always
-ExecStart=/usr/local/bin/matrix-conduit
-
-[Install]
-WantedBy=multi-user.target
-```
-
-Finally, run
-
-```bash
-$ sudo systemctl daemon-reload
-```
-
-
-## Creating the Conduit configuration file
-
-Now we need to create the Conduit's config file in `/etc/matrix-conduit/conduit.toml`. Paste this in **and take a moment to read it. You need to change at least the server name.**
-
-```toml
-[global]
-# The server_name is the name of this server. It is used as a suffix for user
-# and room ids. Examples: matrix.org, conduit.rs
-# The Conduit server needs to be reachable at https://your.server.name/ on port
-# 443 (client-server) and 8448 (federation) OR you can create /.well-known
-# files to redirect requests. See
-# https://matrix.org/docs/spec/client_server/latest#get-well-known-matrix-client
-# and https://matrix.org/docs/spec/server_server/r0.1.4#get-well-known-matrix-server
-# for more information
-
-# YOU NEED TO EDIT THIS
-#server_name = "your.server.name"
-
-# This is the only directory where Conduit will save its data
-database_path = "/var/lib/matrix-conduit/conduit_db"
-
-# The port Conduit will be running on. You need to set up a reverse proxy in
-# your web server (e.g. apache or nginx), so all requests to /_matrix on port
-# 443 and 8448 will be forwarded to the Conduit instance running on this port
-port = 6167
-
-# Max size for uploads
-max_request_size = 20_000_000 # in bytes
-
-# Disabling registration means no new users will be able to register on this server
-allow_registration = false
-
-# Disable encryption, so no new encrypted rooms can be created
-# Note: existing rooms will continue to work
-allow_encryption = true
-allow_federation = true
-
-trusted_servers = ["matrix.org"]
-
-#cache_capacity = 1073741824 # in bytes, 1024 * 1024 * 1024
-#max_concurrent_requests = 100 # How many requests Conduit sends to other servers at the same time
-#workers = 4 # default: cpu core count * 2
-
-address = "127.0.0.1" # This makes sure Conduit can only be reached using the reverse proxy
-```
-
-## Setting the correct file permissions
-
-As we are using a Conduit specific user we need to allow it to read the config.
-To do that you can run this command on Debian:
-
-```
-sudo chown -R conduit:nogroup /etc/matrix-conduit
-```
-
-If you use the default database path you also need to run this:
-
-```
-sudo mkdir -p /var/lib/matrix-conduit/conduit_db
-sudo chown -R conduit:nogroup /var/lib/matrix-conduit/conduit_db
-```
-
-
-## Setting up the Reverse Proxy
-
-This depends on whether you use Apache, Nginx or another web server.
-
-### Apache
-
-Create `/etc/apache2/sites-enabled/050-conduit.conf` and copy-and-paste this:
-
-```
-Listen 8448
-
-<VirtualHost *:443 *:8448>
-
-ServerName your.server.name # EDIT THIS
-
-AllowEncodedSlashes NoDecode
-ProxyPass /_matrix/ http://127.0.0.1:6167/_matrix/ nocanon
-ProxyPassReverse /_matrix/ http://127.0.0.1:6167/_matrix/
-
-Include /etc/letsencrypt/options-ssl-apache.conf
-SSLCertificateFile /etc/letsencrypt/live/your.server.name/fullchain.pem # EDIT THIS
-SSLCertificateKeyFile /etc/letsencrypt/live/your.server.name/privkey.pem # EDIT THIS
-</VirtualHost>
-```
-
-**You need to make some edits again.** When you are done, run
-
-```bash
-$ sudo systemctl reload apache2
-```
-
-
-### Nginx
-
-If you use Nginx and not Apache, add the following server section inside the
-http section of `/etc/nginx/nginx.conf`
-
-```
-server {
-    listen 443 ssl http2;
-    listen [::]:443 ssl http2;
-    listen 8448 ssl http2;
-    listen [::]:8448 ssl http2;
-    server_name your.server.name; # EDIT THIS
-    merge_slashes off;
-
-    location /_matrix/ {
-        proxy_pass http://127.0.0.1:6167$request_uri;
-        proxy_set_header Host $http_host;
-        proxy_buffering off;
-    }
-
-    ssl_certificate /etc/letsencrypt/live/your.server.name/fullchain.pem; # EDIT THIS
-    ssl_certificate_key /etc/letsencrypt/live/your.server.name/privkey.pem; # EDIT THIS
-    ssl_trusted_certificate /etc/letsencrypt/live/your.server.name/chain.pem; # EDIT THIS
-    include /etc/letsencrypt/options-ssl-nginx.conf;
-}
-```
-**You need to make some edits again.** When you are done, run
-
-```bash
-$ sudo systemctl reload nginx
-```
-
-
-## SSL Certificate
-
-The easiest way to get an SSL certificate, if you don't have one already, is to install `certbot` and run this:
-
-```bash
-$ sudo certbot -d your.server.name
-```
-
-
-## You're done!
-
-Now you can start Conduit with:
-
-```bash
-$ sudo systemctl start conduit
-```
-
-Set it to start automatically when your system boots with:
-
-```bash
-$ sudo systemctl enable conduit
-```
-
-If you want to set up an appservice, take a look at the [Appservice Guide](APPSERVICES.md).

 # Conduit
+
+<!-- ANCHOR: catchphrase -->
 ### A Matrix homeserver written in Rust
+<!-- ANCHOR_END: catchphrase -->
+
+Please visit the [Conduit documentation](https://famedly.gitlab.io/conduit) for more information.
+Alternatively you can open [docs/introduction.md](docs/introduction.md) in this repository.
+
+<!-- ANCHOR: body -->
+#### What is Matrix?
+
+[Matrix](https://matrix.org) is an open network for secure and decentralized
+communication. Users from every Matrix homeserver can chat with users from all
+other Matrix servers. You can even use bridges (also called Matrix appservices)
+to communicate with users outside of Matrix, like a community on Discord.
 
 #### What is the goal?
 
-A fast Matrix homeserver that's easy to set up and just works. You can install
+An efficient Matrix homeserver that's easy to set up and just works. You can install
 it on a mini-computer like the Raspberry Pi to host Matrix for your family,
 friends or company.
 
-
 #### Can I try it out?
 
-Yes! Just open a Matrix client (<https://app.element.io> or Element Android for
-example) and register on the `https://conduit.koesters.xyz` homeserver.
-
-
-#### What is it built on?
-
-- [Ruma](https://www.ruma.io): Useful structures for endpoint requests and
-  responses that can be (de)serialized
-- [Sled](https://github.com/spacejam/sled): A simple (key, value) database with
-  good performance
-- [Rocket](https://rocket.rs): A flexible web framework
+Yes! You can test our Conduit instance by opening a client that supports registration tokens such as [Element web](https://app.element.io/), [Nheko](https://matrix.org/ecosystem/clients/nheko/) or [SchildiChat web](https://app.schildi.chat/) and registering on the `conduit.rs` homeserver. The registration token is "for_testing_only". Don't share personal information. Once you have registered, you can use any other [Matrix client](https://matrix.org/ecosystem/clients) to login.
 
+Server hosting for conduit.rs is donated by the Matrix.org Foundation.
 
 #### What is the current status?
 
-Conduit can already be used chat with other users on Conduit, chat with users
-from other Matrix servers and even to chat with users on other platforms using
-appservices. When chatting with users on the same Conduit server, everything
-should work assuming you use a compatible client.
-
-**You should not join Matrix rooms without asking the admins first.** We do not
-know whether Conduit is safe for general use yet, so you should assume there is
-some chance that it breaks rooms permanently for all participating users. We
-are not aware of such a bug today, but we would like to do more testing.
+Conduit is Beta, meaning you can join and participate in most
+Matrix rooms, but not all features are supported and you might run into bugs
+from time to time.
 
 There are still a few important features missing:
 
-- Database stability (currently you might have to do manual upgrades or even wipe the db for new versions)
-- End-to-end encrypted chats over federation
-- Typing, presence, read receipts etc. over federation
-- Lots of testing
-
-Check out the [Conduit 1.0 Release Milestone](https://gitlab.com/famedly/conduit/-/milestones/3).
-
-
-#### How can I deploy my own?
-
-##### Deploy
-
-Download or compile a Conduit binary, set up the config and call it from somewhere like a systemd script. [Read
-more](DEPLOY.md)
-
-If you want to connect an Appservice to Conduit, take a look at the [Appservice Guide](APPSERVICES.md).
-
-##### Deploy using a Debian package
-
-You need to have the `deb` helper command installed that creates Debian packages from Cargo projects (see [cargo-deb](https://github.com/mmstick/cargo-deb/) for more info):
-
-```shell
-$ cargo install cargo-deb
-```
-
-Then, you can create and install a Debian package at a whim:
-
-```shell
-$ cargo deb
-$ dpkg -i target/debian/matrix-conduit_0.1.0_amd64.deb
-```
-
-This will build, package, install, configure and start Conduit. [Read more](debian/README.Debian).
-
-Note that `cargo deb` supports [cross-compilation](https://github.com/mmstick/cargo-deb/#cross-compilation) too!
-Official Debian packages will follow once Conduit starts to have stable releases.
-
-##### Deploy using Docker
-
-Pull and run the docker image with
-
-``` bash
-docker pull matrixconduit/matrix-conduit:latest
-docker run -d -p 8448:8000 -v ~/conduit.toml:/srv/conduit/conduit.toml -v db:/srv/conduit/.local/share/conduit matrixconduit/matrix-conduit:latest
-```
-
-> <b>Note:</b> You also need to supply a `conduit.toml` config file, you can find an example [here](./conduit-example.toml).
-> Or you can pass in `-e CONDUIT_CONFIG=""` and configure Conduit purely with env vars.
-
-Or build and run it with docker or docker-compose. [Read more](docker/README.md)

-# Deploy using Docker
-
-> **Note:** To run and use Conduit you should probably use it with a Domain or Subdomain behind a reverse proxy (like Nginx, Traefik, Apache, ...) with a Lets Encrypt certificate.
-
-
-## Docker
-
-### Build & Dockerfile
-
-The Dockerfile provided by Conduit has two stages, each of which creates an image.
-1. **Builder:** Builds the binary from local context or by cloning a git revision from the official repository.
-2. **Runtime:** Copies the built binary from **Builder** and sets up the runtime environment, like creating a volume to persist the database and applying the correct permissions.
-
-The Dockerfile includes a few build arguments that should be supplied when building it.
-
-``` Dockerfile
-ARG LOCAL=false
-ARG CREATED
-ARG VERSION
-ARG GIT_REF=origin/master
-```
-
-- **CREATED:** Date and time as string (date-time as defined by RFC 3339). Will be used to create the Open Container Initiative compliant label `org.opencontainers.image.created`. Supply by it like this `$(date -u +'%Y-%m-%dT%H:%M:%SZ')`
-- **VERSION:** The SemVer version of Conduit, which is in the image. Will be used to create the Open Container Initiative compliant label `org.opencontainers.image.version`. If you have a `Cargo.toml` in your build context, you can get it with `$(grep -m1 -o '[0-9].[0-9].[0-9]' Cargo.toml)`
-- **LOCAL:** *(Optional)* A boolean value, specifies if the local build context should be used, or if the official repository will be cloned. If not supplied with the build command, it will default to `false`.
-- **GIT_REF:** *(Optional)* A git ref, like `HEAD` or a commit ID. The supplied ref will be used to create the Open Container Initiative compliant label `org.opencontainers.image.revision` and will be the ref that is cloned from the repository when not building from the local context. If not supplied with the build command, it will default to `origin/master`.
-
-To build the image you can use the following command
-
-``` bash
-docker build . -t matrixconduit/matrix-conduit:latest --build-arg CREATED=$(date -u +'%Y-%m-%dT%H:%M:%SZ') --build-arg VERSION=$(grep -m1 -o '[0-9].[0-9].[0-9]' Cargo.toml)
-```
-
-which also will tag the resulting image as `matrixconduit/matrix-conduit:latest`.
-**Note:** it ommits the two optional `build-arg`s.
-
-
-### Run
-
-After building the image you can simply run it with
-
-``` bash
-docker run -d -p 8448:8000 -v ~/conduit.toml:/srv/conduit/conduit.toml -v db:/srv/conduit/.local/share/conduit matrixconduit/matrix-conduit:latest
-```
-
-For detached mode, you also need to use the `-d` flag. You also need to supply a `conduit.toml` config file, you can find an example [here](../conduit-example.toml).
-You can pass in different env vars to change config values on the fly. You can even configure Conduit completely by using env vars, but for that you need
-too pass `-e CONDUIT_CONFIG=""` into your container. For an overview of possible values, please take a look at the `docker-compose.yml` file.
-If you just want to test Conduit for a short time, you can use the `--rm` flag, which will clean up everything related to your container after you stop it.
-
-
-## Docker-compose
-
-If the docker command is not for you or your setup, you can also use one of the provided `docker-compose` files. Depending on your proxy setup, use the [`docker-compose.traefik.yml`](docker-compose.traefik.yml) including [`docker-compose.override.traefik.yml`](docker-compose.override.traefik.yml) or the normal [`docker-compose.yml`](../docker-compose.yml) for every other reverse proxy.
-
-
-### Build
-
-To build the Conduit image with docker-compose, you first need to open and modify the `docker-compose.yml` file. There you need to comment the `image:` option and uncomment the `build:` option. Then call docker-compose with:
-
-``` bash
-CREATED=$(date -u +'%Y-%m-%dT%H:%M:%SZ') VERSION=$(grep -m1 -o '[0-9].[0-9].[0-9]' Cargo.toml) docker-compose up
-```
-
-This will also start the container right afterwards, so if want it to run in detached mode, you also should use the `-d` flag. For possible `build-args`, please take a look at the above `Build & Dockerfile` section.
-
-
-### Run
-
-If you already have built the image, you can just start the container and everything else in the compose file in detached mode with:
-
-``` bash
-docker-compose up -d
-```

+### TLS
+The `tls` table contains the following fields:
+- `certs`: The path to the public PEM certificate
+- `key`: The path to the PEM private key
+
+#### Example
+```toml
+[global.tls]
+certs = "/path/to/cert.pem"
+key = "/path/to/key.pem"
+```
+
+
+### Proxy
+You can choose what requests conduit should proxy (if any). The `proxy` table contains the following fields
+
+#### Global
+The global option will proxy all outgoing requests. The `global` table contains the following fields:
+- `url`: The URL of the proxy server
+##### Example
+```toml
+[global.proxy.global]
+url = "https://example.com"
+```
+
+#### By domain
+An array of tables that contain the following fields:
+- `url`: The URL of the proxy server
+- `include`: Domains that should be proxied (assumed to be `["*"]` if unset)
+- `exclude`: Domains that should not be proxied (takes precedent over `include`)
+
+Both `include` and `exclude` allow for glob pattern matching.
+##### Example
+In this example, all requests to domains ending in `.onion` and `matrix.secretly-an-onion-domain.xyz` 
+will be proxied via `socks://localhost:9050`, except for domains ending in `.myspecial.onion`. You can add as many `by_domain` tables as you need.
+```toml
+[[global.proxy.by_domain]]
+url = "socks5://localhost:9050"
+include = ["*.onion", "matrix.secretly-an-onion-domain.xyz"]
+exclude = ["*.clearnet.onion"]
+```
+
+### Example
+
+> **Note:** The following example is a minimal configuration file. You should replace the values with your own.
+
+```toml
+[global]
+{{#include ../conduit-example.toml:22:}}
+```

+# Delegation
+
+You can run Conduit on a separate domain than the actual server name (what shows up in user ids, aliases, etc.).
+For example you can have your users have IDs such as `@foo:example.org` and have aliases like `#bar:example.org`,
+while actually having Conduit hosted on the `matrix.example.org` domain. This is called delegation.
+
+## Automatic (recommended)
+
+Conduit has support for hosting delegation files by itself, and by default uses it to serve federation traffic on port 443.
+
+With this method, you need to direct requests to `/.well-known/matrix/*` to Conduit in your reverse proxy.
+
+This is only recommended if Conduit is on the same physical server as the server which serves your server name (e.g. example.org)
+as servers don't always seem to cache the response, leading to slower response times otherwise, but it should also work if you
+are connected to the server running Conduit using something like a VPN.
+
+> **Note**: this will automatically allow you to use [sliding sync][0] without any extra configuration
+
+To configure it, use the following options:
+| Field | Type | Description | Default |
+| --- | --- | --- | --- |
+| `well_known_client` | `String` | The URL that clients should use to connect to Conduit | `https://<server_name>` |
+| `well_known_server` | `String` | The hostname and port servers should use to connect to Conduit | `<server_name>:443` |
+
+### Example
+
+```toml
+[global]
+well_known_client = "https://matrix.example.org"
+well_known_server = "matrix.example.org:443"
+```
+
+## Manual
+
+Alternatively you can serve static JSON files to inform clients and servers how to connect to Conduit.
+
+### Servers
+
+For servers to discover how to access your domain, serve a response in the following format for `/.well-known/matrix/server`:
+
+```json
+{
+  "m.server": "matrix.example.org:443"
+}
+```
+Where `matrix.example.org` is the domain and `443` is the port Conduit is accessible at.
+
+### Clients
+
+For clients to discover how to access your domain, serve a response in the following format for `/.well-known/matrix/client`:
+```json
+{
+  "m.homeserver": {
+    "base_url": "https://matrix.example.org"
+  }
+}
+```
+Where `matrix.example.org` is the URL Conduit is accessible at.
+
+To ensure that all clients can access this endpoint, it is recommended you set the following headers for this endpoint:
+```
+Access-Control-Allow-Origin: *
+Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS
+Access-Control-Allow-Headers: X-Requested-With, Content-Type, Authorization
+```
+

+# Conduit for Docker
+
+> **Note:** To run and use Conduit you should probably use it with a Domain or Subdomain behind a reverse proxy (like Nginx, Traefik, Apache, ...) with a Lets Encrypt certificate.
+
+## Docker
+
+To run Conduit with Docker you can either build the image yourself or pull it from a registry.
+
+
+### Use a registry
+
+OCI images for Conduit are available in the registries listed below. We recommend using the image tagged as `latest` from GitLab's own registry.
+
+| Registry        | Image                                                           | Size                          | Notes                  |
+| --------------- | --------------------------------------------------------------- | ----------------------------- | ---------------------- |
+| GitLab Registry | [registry.gitlab.com/famedly/conduit/matrix-conduit:latest][gl] | ![Image Size][shield-latest]  | Stable image.          |
+| Docker Hub      | [docker.io/matrixconduit/matrix-conduit:latest][dh]             | ![Image Size][shield-latest]  | Stable image.          |
+| GitLab Registry | [registry.gitlab.com/famedly/conduit/matrix-conduit:next][gl]   | ![Image Size][shield-next]    | Development version.   |
+| Docker Hub      | [docker.io/matrixconduit/matrix-conduit:next][dh]               | ![Image Size][shield-next]    | Development version.   |
+
+
+[dh]: https://hub.docker.com/r/matrixconduit/matrix-conduit
+[gl]: https://gitlab.com/famedly/conduit/container_registry/2497937
+[shield-latest]: https://img.shields.io/docker/image-size/matrixconduit/matrix-conduit/latest
+[shield-next]: https://img.shields.io/docker/image-size/matrixconduit/matrix-conduit/next
+
+
+Use 
+```bash
+docker image pull <link>
+```
+to pull it to your machine.
+
+
+
+### Build using a dockerfile
+
+The Dockerfile provided by Conduit has two stages, each of which creates an image.
+
+1. **Builder:** Builds the binary from local context or by cloning a git revision from the official repository.
+2. **Runner:** Copies the built binary from **Builder** and sets up the runtime environment, like creating a volume to persist the database and applying the correct permissions.
+
+To build the image you can use the following command
+
+```bash
+docker build --tag matrixconduit/matrix-conduit:latest .
+```
+
+which also will tag the resulting image as `matrixconduit/matrix-conduit:latest`.
+
+
+
+### Run
+
+When you have the image you can simply run it with
+
+```bash
+docker run -d -p 8448:6167 \
+  -v db:/var/lib/matrix-conduit/ \
+  -e CONDUIT_SERVER_NAME="your.server.name" \
+  -e CONDUIT_DATABASE_BACKEND="rocksdb" \
+  -e CONDUIT_ALLOW_REGISTRATION=true \
+  -e CONDUIT_ALLOW_FEDERATION=true \
+  -e CONDUIT_MAX_REQUEST_SIZE="20000000" \
+  -e CONDUIT_TRUSTED_SERVERS="[\"matrix.org\"]" \
+  -e CONDUIT_MAX_CONCURRENT_REQUESTS="100" \
+  -e CONDUIT_PORT="6167" \
+  --name conduit <link>
+```
+
+or you can use [docker compose](#docker-compose).
+
+The `-d` flag lets the container run in detached mode. You now need to supply a `conduit.toml` config file, an example can be found [here](../configuration.md).
+You can pass in different env vars to change config values on the fly. You can even configure Conduit completely by using env vars, but for that you need
+to pass `-e CONDUIT_CONFIG=""` into your container. For an overview of possible values, please take a look at the `docker-compose.yml` file.
+
+If you just want to test Conduit for a short time, you can use the `--rm` flag, which will clean up everything related to your container after you stop it.
+
+### Docker compose
+
+If the `docker run` command is not for you or your setup, you can also use one of the provided `docker compose` files.
+
+Depending on your proxy setup, you can use one of the following files;
+- If you already have a `traefik` instance set up, use [`docker-compose.for-traefik.yml`](docker-compose.for-traefik.yml)
+- If you don't have a `traefik` instance set up (or any other reverse proxy), use [`docker-compose.with-traefik.yml`](docker-compose.with-traefik.yml)
+- For any other reverse proxy, use [`docker-compose.yml`](docker-compose.yml)
+
+When picking the traefik-related compose file, rename it so it matches `docker-compose.yml`, and
+rename the override file to `docker-compose.override.yml`. Edit the latter with the values you want
+for your server.
+Additional info about deploying Conduit can be found [here](generic.md).
+
+### Build
+
+To build the Conduit image with docker compose, you first need to open and modify the `docker-compose.yml` file. There you need to comment the `image:` option and uncomment the `build:` option. Then call docker compose with:
+
+```bash
+docker compose up
+```
+
+This will also start the container right afterwards, so if want it to run in detached mode, you also should use the `-d` flag.
+
+### Run
+
+If you already have built the image or want to use one from the registries, you can just start the container and everything else in the compose file in detached mode with:
+
+```bash
+docker compose up -d
+```
+
+> **Note:** Don't forget to modify and adjust the compose file to your needs.
+
+### Use Traefik as Proxy
+
+As a container user, you probably know about Traefik. It is a easy to use reverse proxy for making
+containerized app and services available through the web. With the two provided files,
+[`docker-compose.for-traefik.yml`](docker-compose.for-traefik.yml) (or
+[`docker-compose.with-traefik.yml`](docker-compose.with-traefik.yml)) and
+[`docker-compose.override.yml`](docker-compose.override.yml), it is equally easy to deploy
+and use Conduit, with a little caveat. If you already took a look at the files, then you should have
+seen the `well-known` service, and that is the little caveat. Traefik is simply a proxy and
+loadbalancer and is not able to serve any kind of content, but for Conduit to federate, we need to
+either expose ports `443` and `8448` or serve two endpoints `.well-known/matrix/client` and
+`.well-known/matrix/server`.
+
+With the service `well-known` we use a single `nginx` container that will serve those two files.
+
+So...step by step:
+
+1. Copy [`docker-compose.for-traefik.yml`](docker-compose.for-traefik.yml) (or
+[`docker-compose.with-traefik.yml`](docker-compose.with-traefik.yml)) and [`docker-compose.override.yml`](docker-compose.override.yml) from the repository and remove `.for-traefik` (or `.with-traefik`) from the filename.
+2. Open both files and modify/adjust them to your needs. Meaning, change the `CONDUIT_SERVER_NAME` and the volume host mappings according to your needs.
+3. Create the `conduit.toml` config file, an example can be found [here](../configuration.md), or set `CONDUIT_CONFIG=""` and configure Conduit per env vars.
+4. Uncomment the `element-web` service if you want to host your own Element Web Client and create a `element_config.json`.
+5. Create the files needed by the `well-known` service.
+
+   - `./nginx/matrix.conf` (relative to the compose file, you can change this, but then also need to change the volume mapping)
+
+     ```nginx
+     server {
+         server_name <SUBDOMAIN>.<DOMAIN>;
+         listen      80 default_server;
+
+         location /.well-known/matrix/server {
+            return 200 '{"m.server": "<SUBDOMAIN>.<DOMAIN>:443"}';
+            types { } default_type "application/json; charset=utf-8";
+         }
+
+        location /.well-known/matrix/client {
+            return 200 '{"m.homeserver": {"base_url": "https://<SUBDOMAIN>.<DOMAIN>"}}';
+            types { } default_type "application/json; charset=utf-8";
+            add_header "Access-Control-Allow-Origin" *;
+        }
+
+        location / {
+            return 404;
+        }
+     }
+     ```
+
+6. Run `docker compose up -d`
+7. Connect to your homeserver with your preferred client and create a user. You should do this immediately after starting Conduit, because the first created user is the admin.
+
+
+
+
+## Voice communication
+
+In order to make or receive calls, a TURN server is required. Conduit suggests using [Coturn](https://github.com/coturn/coturn) for this purpose, which is also available as a Docker image. Before proceeding with the software installation, it is essential to have the necessary configurations in place.
+
+### Configuration
+
+Create a configuration file called `coturn.conf` containing:
+
+```conf
+use-auth-secret
+static-auth-secret=<a secret key>
+realm=<your server domain>
+```
+A common way to generate a suitable alphanumeric secret key is by using `pwgen -s 64 1`.
+
+These same values need to be set in conduit. You can either modify conduit.toml to include these lines:
+```
+turn_uris = ["turn:<your server domain>?transport=udp", "turn:<your server domain>?transport=tcp"]
+turn_secret = "<secret key from coturn configuration>"
+```
+or append the following to the docker environment variables dependig on which configuration method you used earlier:
+```yml
+CONDUIT_TURN_URIS: '["turn:<your server domain>?transport=udp", "turn:<your server domain>?transport=tcp"]'
+CONDUIT_TURN_SECRET: "<secret key from coturn configuration>"
+```
+Restart Conduit to apply these changes.
+
+### Run
+Run the [Coturn](https://hub.docker.com/r/coturn/coturn) image using 
+```bash
+docker run -d --network=host -v $(pwd)/coturn.conf:/etc/coturn/turnserver.conf coturn/coturn
+```
+
+or docker compose. For the latter, paste the following section into a file called `docker-compose.yml`
+and run `docker compose up -d` in the same directory.
+
+```yml
+version: 3
+services:
+    turn:
+      container_name: coturn-server
+      image: docker.io/coturn/coturn
+      restart: unless-stopped
+      network_mode: "host"
+      volumes:
+        - ./coturn.conf:/etc/coturn/turnserver.conf
+```
+
+To understand why the host networking mode is used and explore alternative configuration options, please visit the following link: https://github.com/coturn/coturn/blob/master/docker/coturn/README.md.
+For security recommendations see Synapse's [Coturn documentation](https://github.com/matrix-org/synapse/blob/develop/docs/setup/turn/coturn.md#configuration).

+> If you run into any problems while setting up Conduit, write an email to `conduit@koesters.xyz`, ask us
+> in `#conduit:fachschaften.org` or [open an issue on GitLab](https://gitlab.com/famedly/conduit/-/issues/new).
+
+## Installing Conduit
+
+Although you might be able to compile Conduit for Windows, we do recommend running it on a Linux server. We therefore
+only offer Linux binaries.
+
+You may simply download the binary that fits your machine. Run `uname -m` to see what you need. For `arm`, you should use `aarch`. Now copy the appropriate url:
+
+**Stable/Main versions:**
+
+| Target | Type | Download |

+
+These builds were created on and linked against the glibc version shipped with Debian bullseye.
+If you use a system with an older glibc version (e.g. RHEL8), you might need to compile Conduit yourself.
+
+**Latest/Next versions:**

+
+```bash
+$ sudo wget -O /usr/local/bin/matrix-conduit <url>
+$ sudo chmod +x /usr/local/bin/matrix-conduit
+```
+
+Alternatively, you may compile the binary yourself. First, install any dependencies:
+
+```bash
+# Debian
+$ sudo apt install libclang-dev build-essential
+
+# RHEL
+$ sudo dnf install clang
+```
+Then, `cd` into the source tree of conduit-next and run:
+```bash
+$ cargo build --release
+```
+
+## Adding a Conduit user
+
+While Conduit can run as any user it is usually better to use dedicated users for different services. This also allows
+you to make sure that the file permissions are correctly set up.
+
+In Debian or RHEL, you can use this command to create a Conduit user:
+
+```bash
+sudo adduser --system conduit --group --disabled-login --no-create-home
+```
+
+## Forwarding ports in the firewall or the router
+
+Conduit uses the ports 443 and 8448 both of which need to be open in the firewall.
+
+If Conduit runs behind a router or in a container and has a different public IP address than the host system these public ports need to be forwarded directly or indirectly to the port mentioned in the config.
+
+## Optional: Avoid port 8448
+
+If Conduit runs behind Cloudflare reverse proxy, which doesn't support port 8448 on free plans, [delegation](https://matrix-org.github.io/synapse/latest/delegate.html) can be set up to have federation traffic routed to port 443:
+```apache
+# .well-known delegation on Apache
+<Files "/.well-known/matrix/server">
+    ErrorDocument 200 '{"m.server": "your.server.name:443"}'
+    Header always set Content-Type application/json
+    Header always set Access-Control-Allow-Origin *
+</Files>
+```
+[SRV DNS record](https://spec.matrix.org/latest/server-server-api/#resolving-server-names) delegation is also [possible](https://www.cloudflare.com/en-gb/learning/dns/dns-records/dns-srv-record/).
+
+## Setting up a systemd service
+
+Now we'll set up a systemd service for Conduit, so it's easy to start/stop Conduit and set it to autostart when your
+server reboots. Simply paste the default systemd service you can find below into
+`/etc/systemd/system/conduit.service`.
+
+```systemd
+[Unit]
+Description=Conduit Matrix Server
+After=network.target
+
+[Service]
+Environment="CONDUIT_CONFIG=/etc/matrix-conduit/conduit.toml"
+User=conduit
+Group=conduit
+Restart=always
+ExecStart=/usr/local/bin/matrix-conduit
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Finally, run
+
+```bash
+$ sudo systemctl daemon-reload
+```
+
+## Creating the Conduit configuration file
+
+Now we need to create the Conduit's config file in
+`/etc/matrix-conduit/conduit.toml`. Paste in the contents of
+[`conduit-example.toml`](../configuration.md) **and take a moment to read it.
+You need to change at least the server name.**
+You can also choose to use a different database backend, but right now only `rocksdb` and `sqlite` are recommended.
+
+## Setting the correct file permissions
+
+As we are using a Conduit specific user we need to allow it to read the config. To do that you can run this command on
+Debian or RHEL:
+
+```bash
+sudo chown -R root:root /etc/matrix-conduit
+sudo chmod 755 /etc/matrix-conduit
+```
+
+If you use the default database path you also need to run this:
+
+```bash
+sudo mkdir -p /var/lib/matrix-conduit/
+sudo chown -R conduit:conduit /var/lib/matrix-conduit/
+sudo chmod 700 /var/lib/matrix-conduit/
+```
+
+## Setting up the Reverse Proxy
+
+This depends on whether you use Apache, Caddy, Nginx or another web server.
+
+### Apache
+
+Create `/etc/apache2/sites-enabled/050-conduit.conf` and copy-and-paste this:
+
+```apache
+# Requires mod_proxy and mod_proxy_http
+#
+# On Apache instance compiled from source,
+# paste into httpd-ssl.conf or httpd.conf
+
+Listen 8448
+
+<VirtualHost *:443 *:8448>
+
+ServerName your.server.name # EDIT THIS
+
+AllowEncodedSlashes NoDecode
+ProxyPass /_matrix/ http://127.0.0.1:6167/_matrix/ timeout=300 nocanon
+ProxyPassReverse /_matrix/ http://127.0.0.1:6167/_matrix/
+
+</VirtualHost>
+```
+
+**You need to make some edits again.** When you are done, run
+
+```bash
+# Debian
+$ sudo systemctl reload apache2
+
+# Installed from source
+$ sudo apachectl -k graceful
+```
+
+### Caddy
+
+Create `/etc/caddy/conf.d/conduit_caddyfile` and enter this (substitute for your server name).
+
+```caddy
+your.server.name, your.server.name:8448 {
+        reverse_proxy /_matrix/* 127.0.0.1:6167
+}
+```
+
+That's it! Just start or enable the service and you're set.
+
+```bash
+$ sudo systemctl enable caddy
+```
+
+### Nginx
+
+If you use Nginx and not Apache, add the following server section inside the http section of `/etc/nginx/nginx.conf`
+
+```nginx
+server {
+    listen 443 ssl http2;
+    listen [::]:443 ssl http2;
+    listen 8448 ssl http2;
+    listen [::]:8448 ssl http2;
+    server_name your.server.name; # EDIT THIS
+    merge_slashes off;
+
+    # Nginx defaults to only allow 1MB uploads
+    # Increase this to allow posting large files such as videos
+    client_max_body_size 20M;
+
+    location /_matrix/ {
+        proxy_pass http://127.0.0.1:6167;
+        proxy_set_header Host $http_host;
+        proxy_buffering off;
+        proxy_read_timeout 5m;
+    }
+
+    ssl_certificate /etc/letsencrypt/live/your.server.name/fullchain.pem; # EDIT THIS
+    ssl_certificate_key /etc/letsencrypt/live/your.server.name/privkey.pem; # EDIT THIS
+    ssl_trusted_certificate /etc/letsencrypt/live/your.server.name/chain.pem; # EDIT THIS
+    include /etc/letsencrypt/options-ssl-nginx.conf;
+}
+```
+
+**You need to make some edits again.** When you are done, run
+
+```bash
+$ sudo systemctl reload nginx
+```
+
+## SSL Certificate
+
+If you chose Caddy as your web proxy SSL certificates are handled automatically and you can skip this step.
+
+The easiest way to get an SSL certificate, if you don't have one already, is to [install](https://certbot.eff.org/instructions) `certbot` and run this:
+
+```bash
+# To use ECC for the private key, 
+# paste into /etc/letsencrypt/cli.ini:
+# key-type = ecdsa
+# elliptic-curve = secp384r1
+
+$ sudo certbot -d your.server.name
+```
+[Automated renewal](https://eff-certbot.readthedocs.io/en/stable/using.html#automated-renewals) is usually preconfigured.
+
+If using Cloudflare, configure instead the edge and origin certificates in dashboard. In case you’re already running a website on the same Apache server, you can just copy-and-paste the SSL configuration from your main virtual host on port 443 into the above-mentioned vhost.
+
+## You're done!
+
+Now you can start Conduit with:
+
+```bash
+$ sudo systemctl start conduit
+```
+
+Set it to start automatically when your system boots with:
+
+```bash
+$ sudo systemctl enable conduit
+```
+
+## How do I know it works?
+
+You can open [a Matrix client](https://matrix.org/ecosystem/clients), enter your homeserver and try to register. If you are using a registration token, use [Element web](https://app.element.io/), [Nheko](https://matrix.org/ecosystem/clients/nheko/) or [SchildiChat web](https://app.schildi.chat/), as they support this feature.
+
+You can also use these commands as a quick health check.
+
+```bash
+$ curl https://your.server.name/_matrix/client/versions
+
+# If using port 8448
+$ curl https://your.server.name:8448/_matrix/client/versions
+```

+- To check if your server can talk with other homeservers, you can use the [Matrix Federation Tester](https://federationtester.matrix.org/).
+  If you can register but cannot join federated rooms check your config again and also check if the port 8448 is open and forwarded correctly.

+# Conduit for NixOS
+
+Conduit can be acquired by Nix from various places:
+
+* The `flake.nix` at the root of the repo
+* The `default.nix` at the root of the repo
+* From Nixpkgs
+
+The `flake.nix` and `default.nix` do not (currently) provide a NixOS module, so
+(for now) [`services.matrix-conduit`][module] from Nixpkgs should be used to
+configure Conduit.
+
+If you want to run the latest code, you should get Conduit from the `flake.nix`
+or `default.nix` and set [`services.matrix-conduit.package`][package]
+appropriately.

+# FAQ
+
+Here are some of the most frequently asked questions about Conduit, and their answers.
+
+## Why do I get a `M_INCOMPATIBLE_ROOM_VERSION` error when trying to join some rooms?
+
+Conduit doesn't support room versions 1 and 2 at all, and doesn't properly support versions 3-5 currently. You can track the progress of adding support [here](https://gitlab.com/famedly/conduit/-/issues/433).
+
+## How do I backup my server?
+
+To backup your Conduit server, it's very easy.
+You can simply stop Conduit, make a copy or file system snapshot of the database directory, then start Conduit again.
+
+> **Note**: When using a file system snapshot, it is not required that you stop the server, but it is still recommended as it is the safest option and should ensure your database is not left in an inconsistent state.
+
+## How do I setup sliding sync?
+
+If you use the [automatic method for delegation](delegation.md#automatic-recommended) or just proxy `.well-known/matrix/client` to Conduit, sliding sync should work with no extra configuration.
+If you don't, continue below.
+
+You need to add a `org.matrix.msc3575.proxy` field to your `.well-known/matrix/client` response which contains a url which Conduit is accessible behind.
+Here is an example:
+```json
+{
+~  "m.homeserver": {
+~    "base_url": "https://matrix.example.org"
+~  },
+  "org.matrix.msc3575.proxy": {
+    "url": "https://matrix.example.org"
+  }
+}
+```
+
+## Can I migrate from Synapse to Conduit?
+
+Not really. You can reuse the domain of your current server with Conduit, but you will not be able to migrate accounts automatically.
+Rooms that were federated can be re-joined via the other participating servers, however media and the like may be deleted from remote servers after some time, and hence might not be recoverable.
+
+## How do I make someone an admin?
+
+Simply invite them to the admin room. Once joined, they can administer the server by interacting with the `@conduit:<server_name>` user.

+# Setting up TURN/STUN
+
+## General instructions
+
+* It is assumed you have a [Coturn server](https://github.com/coturn/coturn) up and running. See [Synapse reference implementation](https://github.com/element-hq/synapse/blob/develop/docs/turn-howto.md).
+
+## Edit/Add a few settings to your existing conduit.toml
+
+```
+# Refer to your Coturn settings. 
+# `your.turn.url` has to match the REALM setting of your Coturn as well as `transport`.
+turn_uris = ["turn:your.turn.url?transport=udp", "turn:your.turn.url?transport=tcp"]
+
+# static-auth-secret of your turnserver
+turn_secret = "ADD SECRET HERE"
+
+# If you have your TURN server configured to use a username and password
+# you can provide these information too. In this case comment out `turn_secret above`!
+#turn_username = ""
+#turn_password = ""
+```
+
+## Apply settings
+
+Restart Conduit.
