-Plume is a federated blogging engine, based on ActivityPub. It uses the Rocket framework, and Diesel to interact with the database.
+Plume is a **federated blogging engine**, based on *ActivityPub*. It is written in *Rust*, with the *Rocket* framework, and *Diesel* to interact with the database.
+The front-end uses *Ructe* templates, *WASM* and *SCSS*.
 
-It is not yet ready for production use, but we have all the basic features (account management, blogs, articles, comments, etc) and a basic federation.
+## Features
 
-Feel free to join our Matrix room: `#plume:disroot.org` to discuss about the project!
+A lot of features are still missing, but what is already here should be quite stable. Current and planned features include:
 
-We also have a [Loomio group](https://framavox.org/g/WK40YHMA/plume) to debate and vote and features. Feel free to join it to take part in Plume's decision process.
+- **A blog-centric approach**: you can create as much blogs as you want with your account, to keep your different publications separated.
+- **Media management**: you can upload pictures to illustrate your articles, but also audio files if you host a podcast, and manage them all from Plume.
+- **Federation**: Plume is part of a network of interconnected websites called the Fediverse. Each of these websites (often called *instances*) have their own
+rules and thematics, but they can all communicate with each other.
+- **Collaborative writing**: invite other people to your blogs, and write articles together.
