+# Example configuration
 
-**Conduit** is configured using a TOML file. The configuration file is loaded from the path specified by the `CONDUIT_CONFIG` environment variable.
-
-> **Note:** The configuration file is required to run Conduit. If the `CONDUIT_CONFIG` environment variable is not set, Conduit will exit with an error.
-
-> **Note:** If you update the configuration file, you must restart Conduit for the changes to take effect
-
-> **Note:** You can also configure Conduit by using `CONDUIT_{field_name}` environment variables. To set values inside a table, use `CONDUIT_{table_name}__{field_name}`. Example: `CONDUIT_SERVER_NAME="example.org"`
-
-Conduit's configuration file is divided into the following sections:
-
-- [Global](#global)
-    - [TLS](#tls)
-    - [Proxy](#proxy)

-## Global

-### 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:}}
+``` toml
+{{#include ../conduit-example.toml}}

-# 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
-```
-
-If you also want to be able to use [sliding sync][0], look [here](faq.md#how-do-i-setup-sliding-sync).

-# 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.
