Create a branch on Gitlab.

git pull

git checkout <branchname>

Add only files that make up a small and coherent change

git add <file1> <file2> ...

Start an editor which lets you separate the commit message subject from the body.

git commit

Update your feature branch with the latest changes from the master by interactive rebase.

git rebase -i master

If you don’t have conflicts, skip this step. If you have conflicts, resolve them and continue rebase.

git add <file1> <file2> ...

git rebase --continue

Push your branch.

git push

If you change git history on your feature branch you may need to use the -f or --force flag.

Make a Merge Request. Assign peer reviewer.

Merge request will be accepted, merged and closed by a reviewer.

Remove your local feature branch if you're done.

git branch -d <branchname>
