This is the general overview page of the OpenAirInterface documentation.
This page groups links to general information, tutorials, design documents, radio integration, and special-purpose libraries.
**IMPORTANT NOTE:**
Before reading this documentation, we strongly advise you to keep your own repository rebased on `develop`
or at least to checkout the documentation on the version of the repository you are using.
Then the documentation will better reflect the features available in your repository so that you may avoid some errors.
Beware if you previously pulled the `develop` branch that your repository may be now behind `develop`.
