-# Setting up Appservices
-
-## Getting help
-
-If you run into any problems while setting up an Appservice, 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).
-
-## Tested appservices
-
-Here are some appservices we tested and that work with Conduit:
-- matrix-appservice-discord
-- mautrix-hangouts
-- mautrix-telegram
-
-## Set up the appservice
-
-Follow whatever instructions are given by the appservice. This usually includes
-downloading, changing its config (setting domain, homeserver url, port etc.)
-and later starting it.
-
-At some point the appservice guide should ask you to add a registration yaml
-file to the homeserver. In Synapse you would do this by adding the path to the
-homeserver.yaml, but in Conduit you can do this from within Matrix:
-
-First, go into the #admins room of your homeserver. The first person that
-registered on the homeserver automatically joins it. Then send a message into
-the room like this:
-
-    @conduit:your.server.name: register_appservice
-    ```
-    paste
-    the
-    contents
-    of
-    the
-    yaml
-    registration
-    here
-    ```
-
-You can confirm it worked by sending a message like this:
-`@conduit:your.server.name: list_appservices`
-
-The @conduit bot should answer with `Appservices (1): your-bridge`
-
-Then you are done. Conduit will send messages to the appservices and the
-appservice can send requests to the homeserver. You don't need to restart
-Conduit, but if it doesn't work, restarting while the appservice is running
-could help.

+# Configuring Conduit
+
+Conduit can be configured via a config file (conventionally called Conduit.toml) or environment variables. If a config
+file exists and environment variables are set, environment variables overwrite config options.
+
+You absolutely need to set the environment variable `CONDUIT_CONFIG_FILE` to either point to a config file (
+e.g. `CONDUIT_CONFIG_FILE=/etc/conduit/Conduit.toml`) or to an empty string (`CONDUIT_CONFIG_FILE=''`) if you want to
+configure Conduit with just environment variables.
+
+## Mandatory config options
+
+Mandatory variables must be configured in order for Conduit to run properly.
+
+### Server Name
+
+- Config file key: `server_name`
+- Envirnoment variable: `CONDUIT_SERVER_NAME`
+- Default value: _None, you will need to choose your own._
+
+The server_name is the name of this server. It is used as a suffix for user and room ids. Example: If you set it
+to `conduit.rs`, your usernames will look like `@somebody:conduit.rs`.
+
+The Conduit server needs to be reachable at https://your.server.name/ on port 443 (client-server) and 8448 (
+server-server) OR you can create /.well-known files to redirect requests. See
+the [Client-Server specs](https://matrix.org/docs/spec/client_server/latest#get-well-known-matrix-client) and
+the [Server-Server specs](https://matrix.org/docs/spec/server_server/r0.1.4#get-well-known-matrix-server) for more
+information.
+
+### Database Path
+
+- Config file key: `database_path`
+- Envirnoment variable: `CONDUIT_DATABASE_PATH`
+- Default value: _None, but many people like to use `/var/lib/conduit/`_.
+
+A **directory** where Conduit stores its database and media files. This directory must exist, have enough free space and
+be readable and writable by the user Conduit is running as.
+
+What does _enough free space_ mean? It heavily on the amount of messages your Conduit server will see and the amount and
+size of media files users on your Conduit server send. As a rule of thumb, you should have at least 10 GB of free space
+left. You should be comfortable for quite some time with 50 GB.
+
+### TCP Port
+
+- Config file key: `port`
+- Environment variable: `CONDUIT_PORT`
+- Default value: _None, but many people like to use `6167`_.
+
+The TCP port Conduit will listen on for connections. The port needs to be free (no other program is listeing on it).
+
+Conduit does currently (2021-09) not offer HTTPS by itself. Only unencrypted HTTP requests will be accepted on this
+port. Unless you know what you are doing, this port should not be exposed to the internet. Instead, use a reverse proxy
+capable of doing TLS to offer your Conduit server to the internet via HTTPS. See [TODO] for example configurations.
+
+## Optional configuration options
+
+These config options come with defaults and don't need to be configured for Conduit to run. That said, you should still
+check them to make sure that your Conduit server behaves like you want it to do.
+
+### Maximum request size
+
+- Config file key: `max_request_size`
+- Environment variable: `CONDUIT_MAX_REQUEST_SIZE`
+- Default value: `20_000_000` (~= 20 MB)
+
+The maximum size in bytes for incoming requests to Conduit. You can use underscores to improve readability.
+
+This will effectively limit the size for images, videos and other files users on your Conduit server can send.
+
+### Allow Registration?
+
+- Config file key: `allow_registration`
+- Environment variable: `CONDUIT_ALLOW_REGISTRATION`
+- Default value: `true`
+- Possible values: `true`, `false`
+
+It this is set to `false`, no new users can register accounts on your Conduit server. Already registered users will not
+be affected from this setting and can continue to user your server.
+
+The first user to ever register on your Conduit server will be considered the admin account and is automatically invited
+into the admin room.
+
+### Allow Encryption?
+
+- Config file key: `allow_encryption`
+- Environment variable: `CONDUIT_ALLOW_ENCRYPTION`
+- Default value: `true`
+- Possible values: `true`, `false`
+
+If this is set to `false`, Conduit disables the ability for users to create encrypted chats. Existing encrypted chats
+may continue to work.
+
+### Allow federation?
+
+- Config file key: `allow_federation`
+- Environment variable: `CONDUIT_ALLOW_FEDERATION`
+- Default value: `false`
+- Possible values: `true`, `false`
+
+Federation means that users from different Matrix servers can chat with each other. E.g. `@mathew:matrix.org` can chat
+with `@timo:conduit.rs`.
+
+If this option is set to `false`, users on your Conduit server can only talk with other users on your Conduit server.
+
+Federation with other servers needs to happen over HTTPS, so make sure you have set up a reverse proxy.
+
+### Jaeger Tracing
+
+- Config file key: `allow_jaeger`
+- Environment variable: `CONDUIT_ALLOW_JAEGER`
+- Default value: `false`
+- Possible values: `true`, `false`
+
+Enable Jaeger to support monitoring and troubleshooting through Jaeger.
+
+If you don't know what Jaeger is, you can safely leave this set to `false`.
+
+### Trusted servers
+
+- Config file key: `trusted_servers`
+- Environment variable: `CONDUIT_TRUSTED_SERVERS`
+- Default value: `[]`
+- Possible values: JSON-Array of server domains, e.g. `["matrix.org"]` or `["matrix.org", "conduit.rs"]`.
+
+Matrix servers have so-called "server keys", which authenticate messages from their users. Because your Conduit server
+might not know the server keys from every server it encounters, it can ask a _trusted server_ for them. This speeds
+things up for rooms with people from a lot of different servers.
+
+You should only set this to include trustworthy servers. Most people consider a good default to be `["matrix.org"]`.
+
+Only relevant if you have federation enabled.
+
+### Limit amount of concurrent requests
+
+- Config file key: `max_concurrent_requests`
+- Environment variable: `CONDUIT_MAX_CONCURRENT_REQUESTS`
+- Default value: `100`
+- Suggested values: `1` - `1000` (u16)
+
+How many requests Conduit can make at the same time. This affects federation with other Matrix servers, push
+notifications and app_services.
+
+// TODO Timo: When does it make sense to change this?
+
+### Configure logging
+
+- Config file key: `log`
+- Environment variable: `CONDUIT_LOG`
+- Default value: `info,state_res=warn,rocket=off,_=off,sled=off`
+
+Configures which kind of messages Conduit logs.
+
+> // TODO: Better and more thorough explanation
+
+### Worker threads
+
+- Config file key: `workers`
+- Environment variable: `CONDUIT_WORKERS`
+- Default value: cpu core count * 2
+- Possible values: // TODO
+
+> // TODO: Which thing exactly threads? What not?
+
+### Listening address
+
+- Config file key: `address`
+- Environment variable: `CONDUIT_ADDRESS`
+- Default value: `127.0.0.1`
+- Possible values: Valid IP addresses.
+
+Which IP address conduit is listening on. 127.0.0.1 means that Conduit can only be accessed from the same server or
+through a reverse proxy on that server. If you want it to be accessible from any network interface (which you should
+not, because other matrix servers should talk to your Conduit via a reverse proxy and not directly), you can set it
+to `0.0.0.0`.
+
+### Database cache capacity
+
+- Config file key: `db_cache_capacity_mb`
+- Environment variable: `CONDUIT_DB_CACHE_CAPACITY_MB`
+- Default value: `200`
+- Possible values: `true`, `false`
+
+The total amount of memory (RAM) that the database cache will be able to use.
+
+> // TODO: this needs clearification: In RAM or on disk and for what exactly?
+
+### PDU cache capacity
+
+- Config file key: `pdu_cache_capacity`
+- Environment variable: `CONDUIT_PDU_CACHE_CAPACITY`
+- Default value: `100_000`
+- Suggested values: `1_000` - `1_000_000` (u32)
+
+The total capacity (read: number of items) the pdu cache can hold in memory. Setting this to a lower number may slow
+Conduit down, as it must fetch more data from the database. Increasing it will mean that Conduit will start to use more
+memory as the cache slowly fills up.
+
+### SQLite WAL clean interval
+
+- Config file key: `sqlite_wal_clean_second_interval`
+- Environment variable: `CONDUIT_SQLITE_WAL_CLEAN_SECOND_INTERVAL`
+- Default value: `60` (every 60 seconds)
+- Suggested values: `1` - `3600` (u32)
+
+How often the WAL file should be cleaned up. The WAL file will be written to until cleaned up, after which it restarts
+writing from the beginning.
+
+The file's size will correspond to how long it could write to it in one go. (e.g. if conduit writes 100MB of data to the
+database inbetween that period, the file will grow to 100MB). You can read more about that in
+the [SQLite Docs](https://www.sqlite.org/draft/wal.html).
+
+Reducing this down too much can offset the benefits of using a WAL at all. However, having this too high can result in a
+large WAL file.
+
+Only relevant when using SQLite as the database.
+
+### Still undocumented config options
+
+- `tracing_flame`
+- `proxy`
+- `jwt_secret`

+# Conduit
+
+Conduit is a simple, fast and reliable chat server for the [Matrix] protocol written in [Rust].
+
+-----
+> Note: This project is work-in-progress. Do *not* rely on it yet.
+
+## What is Matrix?
+
+[Matrix] is an open network for secure and decentralized
+communication. It allows you to chat with friends even if they are using
+another servers and client. You can even use bridges to communicate with users
+outside of Matrix, like a community on Discord or your family on Hangouts.
+
+## Why Conduit?
+
+Conduit is an open-source server implementation of the [Matrix
+Specification] with a focus on easy setup and low
+system requirements, making it very easy to set up.
+
+Other server implementations try to be extremely scalable, which makes sense if
+the goal is to support millions of users on a single instance, but makes
+smaller deployments a lot more inefficient. Conduit tries to keep it simple but
+takes full advantage of that, for example by using an in-memory database for
+[huge performance gains](https://github.com/timokoesters/romeo-and-juliet-benchmark).
+
+The future for Conduit in peer-to-peer Matrix (every client contains a server)
+is also bright.
+
+Conduit tries to be reliable by using the Rust programming language and paying
+close attention to error handling to make sure that evil clients, misbehaving
+servers or even a partially broken database will not cause the whole server to
+stop working.
+
+## Chat with us!

+# Prerequisites for running Conduit
+
+You'll need:
+
+- A domain. Commonly cost about $10/year.
+- A Linux server with a stable internet connection, at least 500 MB of RAM and some disk space for messages and
+  attachments. Commonly start at $5/month.
+- Some basic knowledge about using a shell, SSH and configuring and protecting a server.
+  
+  
+## A word of caution:
+
+Don't underestimate the toll of administrating your own server.
+Conduit can't protect your conversations if your server gets compromised or deleted.
+
+Make sure that you got:
+
+- Automatic security updates
+    - On Ubuntu/Debian: Set up unattended-upgrades
+    - On RHEL/CentOS: Have a look at yum-cron
+- A firewall blocking all but the needed incoming ports

+# About Matrix Homeservers
+
+Matrix homeservers manage its users chats. Every Matrix username includes the homserver it belongs to:
+`@alice:matrix.org` means that the `matrix.org` homeserver hosts a user called `@alice`.
+Every time someone chats with Alice, the `matrix.org` homeserver stores these messages.
+When `@alice:matrix.org` talks with `@adelaide:matrix.org`, that's easy. Both users use the same server.
+
+But how can `@bob:vector.tld`, who uses the `vector.tld` homeserver, exchange messages with `@alice:matrix.org`?
+This is where it get's a bit more complicated.
+
+## Matrix Homeserver discovery
+
+The Matrix specification specifies multiple ways how servers can discover and then talk to each other.
+Let's look at the most common one:
+
+### .well-known files
+
+At first, the only information a server has about a user (e.g. `@bob:vector.tld`) is its homeserver name: `vector.tld`.
+It then makes a HTTP GET request to `https://vector.tld/.well-known/matrix/server`.
+In the ideal case, this file contains a content like this: 
+
+```json
+{
+  "m.server": "matrix.vector.tld:443"
+}
+```
+
+This translates to: The matrix homeserver software for users with a username ending on `vector.tld`
+can be found at the address `matrix.vector.tld` at port 443 (which is the common port for HTTPS).
+
+The homeserver on it's quest to find `@bob:vector.tld` now contacts `matrix.vector.tld:443` and is then
+able to exchange chat messages with it.
+
+
+### Why so complicated?
+
+Organizations often don't want to run their Matrix server on the same machine that hosts their website,
+but `@foo:matrix.evil.corp` usernames are ugly and everyone wants to be `@foo:evil.corp`.
+
+To solve that problem, Matrix implements this extra step via a .well-known file or a DNS entry.
