+## Code lifecycle
+
+This git repository follows the Gitflow pattern, so make sure to follow the convention.
+
+For instance, create a branch `feature/my-change-title` from `develop`, once good enough to be shared and reviewed create a Pull Request targetting `develop`.
+
+## Code convention
+
+For bash/shell script files, follow the conventions from [Google Style Guide](https://google.github.io/styleguide/shellguide.html).
