Last active August 29, 2015 14:20
This is a example to show a reduced version of gitflow. We are considering two remotes at local repository, the origin (fork) and the upstream (central):
(master) $ # starting a new task
(master) $ git pull --ff-only upstream master
(master) $ git checkout -b feature/new-task
(feature/new-task) $ # some coding
(feature/new-task) $ git add -p
(feature/new-task) $ git commit -m "The answer of all questions of the universe"
(feature/new-task) $ git push origin feature/new-task
(feature/new-task) $ # Do a pull request from feature/new-task to master and wait for coworker acceptance
(feature/new-task) $ git checkout master
(master) $ git pull --ff-only upstream master
