 ## Developing
 
+### Branching, versions, etc
+
+There is a `develop` branch which represents current development state. **All new commits (by me) and merge requests (by others) should go to that branch**.

+
+### Code
+
 Use linters, formatters, etc. VSCode with Go plugin is recommended for developing as it will perform most of linting-formatting
 actions automagically.
