+# 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.
+

+# 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
+    - ufw is an easy interface for the linux firewall
+- Protection against automatic attacks
+    - fail2ban scans logs and bans IPs which try to brute force their way into your server.
+    - Disable ssh login for root and switch from password to key based authentication.
+- Automated backups
+    - Most VPS hosting companies offer whole server backups for a small fee.
+    - Or run your own backup with something like borg.
+- A way to get notified if your disk fills up.
+    - If you send too much cat videos to your friends, Conduit might at some point become unable to
+      store any important messages.

+# 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.
