+# 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.
+

-# Deploying Conduit
-
-> ## Getting help
->
-> 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. Now copy the right url:

-
-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, you might need to compile Conduit yourself.

-```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
-
-```bash
-$ sudo apt install libclang-dev build-essential
-```
-
-```bash
-$ cargo build --release
-```
-
-If you want to cross compile Conduit to another architecture, read the guide below.
-
-<details>
-<summary>Cross compilation</summary>
-
-As easiest way to compile conduit for another platform [cross-rs](https://github.com/cross-rs/cross) is recommended, so install it first.
-
-In order to use RockDB as storage backend append `-latomic` to linker flags.
-
-For example, to build a binary for Raspberry Pi Zero W (ARMv6) you need `arm-unknown-linux-gnueabihf` as compilation
-target.
-
-```bash
-git clone https://gitlab.com/famedly/conduit.git
-cd conduit
-export RUSTFLAGS='-C link-arg=-lgcc -Clink-arg=-latomic -Clink-arg=-static-libgcc'
-cross build --release --no-default-features --features conduit_bin,backend_rocksdb,jemalloc --target=arm-unknown-linux-gnueabihf
-```
-</details>
-
-## 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:
-
-```bash
-sudo adduser --system conduit --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.
-
-## 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.**  
-You can also choose to use a different database backend, but right now only `rocksdb` and `sqlite` are recommended.
-
-```toml
-[global]
-# The server_name is the pretty name of this server. It is used as a suffix for user
-# and room ids. Examples: matrix.org, conduit.rs
-
-# The Conduit server needs all /_matrix/ requests to be reachable at
-# https://your.server.name/ on port 443 (client-server) and 8448 (federation).
-
-# If that's not possible for you, you can create /.well-known files to redirect

-```
-
-## 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:
-
-```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:nogroup /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
-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/
-
-</VirtualHost>
-```
-
-**You need to make some edits again.** When you are done, run
-
-```bash
-$ sudo systemctl reload apache2
-```
-
-### 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
-    client_max_body_size 20M;
-
-    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
-
-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 `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
-```
-
-## How do I know it works?
-
-You can open <https://app.element.io>, enter your homeserver and try to register.
-
-You can also use these commands as a quick health check.
-
-```bash
-$ curl https://your.server.name/_matrix/client/versions
-$ 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.
-
-# What's next?
-
-## Audio/Video calls
-
-For Audio/Video call functionality see the [TURN Guide](TURN.md).
-
-## Appservices
-
-If you want to set up an appservice, take a look at the [Appservice Guide](APPSERVICES.md).

+### 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
+```

+
+## 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.

+
+## 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:

+```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;
+

+```
+
+## 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.

-# Conduit for Nix/NixOS
-
-This guide assumes you have a recent version of Nix (^2.4) installed.
-
-Since Conduit ships as a Nix flake, you'll first need to [enable
-flakes][enable_flakes].
-
-You can now use the usual Nix commands to interact with Conduit's flake. For
-example, `nix run gitlab:famedly/conduit` will run Conduit (though you'll need
-to provide configuration and such manually as usual).
-
-If your NixOS configuration is defined as a flake, you can depend on this flake
-to provide a more up-to-date version than provided by `nixpkgs`. In your flake,
-add the following to your `inputs`:
-
-```nix
-conduit = {
-    url = "gitlab:famedly/conduit";
-
-    # Assuming you have an input for nixpkgs called `nixpkgs`. If you experience
-    # build failures while using this, try commenting/deleting this line. This
-    # will probably also require you to always build from source.
-    inputs.nixpkgs.follows = "nixpkgs";
-};
-```
-
-Next, make sure you're passing your flake inputs to the `specialArgs` argument
-of `nixpkgs.lib.nixosSystem` [as explained here][specialargs]. This guide will
-assume you've named the group `flake-inputs`.
-
-Now you can configure Conduit and a reverse proxy for it. Add the following to
-a new Nix file and include it in your configuration:
-
-```nix
-{ config
-, pkgs
-, flake-inputs
-, ...
-}:
-
-let
-  # You'll need to edit these values
-
-  # The hostname that will appear in your user and room IDs
-  server_name = "example.com";
-
-  # The hostname that Conduit actually runs on
-  #
-  # This can be the same as `server_name` if you want. This is only necessary
-  # when Conduit is running on a different machine than the one hosting your
-  # root domain. This configuration also assumes this is all running on a single
-  # machine, some tweaks will need to be made if this is not the case.
-  matrix_hostname = "matrix.${server_name}";
-
-  # An admin email for TLS certificate notifications
-  admin_email = "admin@${server_name}";
-
-  # These ones you can leave alone
