 # Stable-Baselines3 - Contrib
 
-Contrib package for [Stable-Baselines3](https://github.com/DLR-RM/stable-baselines3) - Experimental code
+Contrib package for [Stable-Baselines3](https://github.com/DLR-RM/stable-baselines3) - Experimental code.
+"sb3-contrib" for short.
 
-**You need the master version of Stable Baselines3**:
-```
-pip install git+https://github.com/DLR-RM/stable-baselines3
-```
+A place for training algorithms and tools that are considered experimental, e.g. implementations of the latest
+publications. Goal is to keep the simplicity, documentation and style of stable-baselines3 but for less matured
+implementations. 
 
-Implemented:
+Why create this repository? Over the span of stable-baselines and stable-baselines3, the community has been eager
+to contribute in form of better logging utilities, environment wrappers, extended support (e.g. different action spaces)
+and learning algorithms. However sometimes these utilities were too niche to be considered for stable-baselines or
+proved to be too difficult to integrate well into existing code without a mess. sb3-contrib aims to fix this by
+not requiring the neatest code integration with existing code and not setting limits on what is too niche: almost everything
+remotely useful goes! We hope this allows to extend the known quality of stable-baselines style and documentation beyond
+the relatively small scope of utilities of the main repository.
+
