 # Conduit
 ### A Matrix homeserver written in Rust
 
-[![Liberapay](https://img.shields.io/liberapay/receives/timokoesters?logo=liberapay)](https://liberapay.com/timokoesters)
-[![Matrix](https://img.shields.io/matrix/conduit:conduit.rs?server_fqdn=conduit.koesters.xyz)](https://matrix.to/#/#conduit:matrix.org)
-
 #### What is the goal?
 
 A fast 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 build 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
+
+
+#### What are the biggest things still missing?
+
+- Most federation features (invites, e2ee)
+- Push notifications on mobile
+- Notification settings
+- Lots of testing
+
+Check out the [Conduit 1.0 Release Milestone](https://gitlab.com/famedly/conduit/-/milestones/3).
+

 #### How can I deploy my own?
