+## Project structure
+
+The rust-sdk consists of multiple crates that can be picked at your convenience:
+
+- **matrix-sdk** - High level client library, with batteries included, you're most likely
+  interested in this.
+- **matrix-sdk-base** - No (network) IO client state machine that can be used to embed a
+  Matrix client in your project or build a full fledged network enabled client
+  lib on top of it.
+- **matrix-sdk-crypto** - No (network) IO encryption state machine that can be
+  used to add Matrix E2EE support to your client or client library.
+
 ## Status
 
-This library is very much work in progress.
+The library is in an alpha state, things that are implemented generally work but
+the API will change in breaking ways.
+
+If you are interested in using the matrix-sdk now is the time to try it out and
+provide feedback.
