 ## Policy for contributing
 * `master` branch is protected, changes can only be made via merge requests.
 * To propose changes:
- * Open an issue to discuss the matter
- * Then open a branch to work on the issue
- * When done, submit a merge request to the master branch.
+ * Open an issue to discuss the matter (in gitlab project page -> issues)
+ * Then open a branch to work on the issue. There are several ways to do this:
+  * Click on 'create branch' on the issue page on gitlab (then `git fetch` and `git checkout <branchname>`) 
+  * In your local space, do `git checkout -b <branchname>` to create a new branch from your current `HEAD`.
+ * When done, `git push` the branch and submit a merge request. 
+  * The link to open the merge request is shown following the commit.
+  * Assign someone (other than yourself) to review the merge request.
+  * Follow up on any questions/comments and optionally amend your branch (and re-push) to fix any new issues that arise.
