+## Development
+
+Development happens in *feature branches* branched of from *develop* branch. And all PRs go back there.
+The branch *release* is a temporary branch from *develop* and will be used for bug fixing before a PR to *main* creates a new release. Commits in main will be marked with tags and the *changelog.txt* file in human readable form describe the new features.
