+## Branches
+
+* ```master``` = latest release, e.g. 2.0.1
+* ```next-release``` = development branch - all new features are merged into this branch until the next version is released. So use this branch as base while developing new features or bugfixes.
+* ```test``` = sandbox branch to test new features or merge requests, or run integration tests. The content of this branch may change at any time.
+
+## Merge Requests
+
+Please create one branch for each feature and send one merge request for each branch.
+
+Dont squash several changes or commits into one merge request as this is hard to review.
+
+Please use ```next-release``` as base branch and send your merge request to this branch (not ```master```).
