Branch from master, naming your branch with your initials, the Tracker Story ID, and a description of the story.
Here is an example branch name:
bgb/24096875_add_vcard_column_auto_mapping
When work on your branch is complete and tested, visit your branch in Github and submit a pull request:
Now you'll be waiting on your pull request to be merged into master.
It's likely your next story will depend upon your previous branch. If your previous branch has yet to be merged into master, you'll need to branch from your previous branch to continue working while you're waiting on the merge.
If your next story does not depend upon your previous branch, or if your previous branch has already been merged into master, you can branch from master.
