Workflow with git

We have a main branch were all the submitted exercise are in. For every new Exercise there
is a new branch called ex1 for exercise one. Everyone creates his own subbranch and from ex1
for example ex1/ax. All work is done on your local branch. If you think you impl a feature
or solved a task. Create a pull request (ex1/ax => ex1) in gitlab. The other group members
will review the changes and make comments, reject or approve the the request. If it gets
approved merge the Pr into the ex1 branch. If the exercise is submit merge the ex1 branch into
the master branch.
