+# Knowledge base
+
+This knowledge base is aimed at helping you solving common issues that you might encounter on your RL journey.
+It is a more practical guide than what one might usually gather from a textbook or a repo.
+It details pro-tips to run models on cluster. It gives indications on how to set up a
+conda environment, how to install packages without sudo access. It
+highlights common issues when installing and running RL libraries and
+provide ready-to-use solution for these issues.
+
+## Contributing
+
+Of course, this is a ever 1% complete journey, and we can't expect to cover all the RL
+field at any point in the future.
+
+**If you feel something is missing**, or if you bump in an issue and think that the
+community might benefit from your experience, please submit a PR with your contribution!
