           When a new branch is created with git branch or git checkout that
           tracks another branch, this variable tells Git to set up pull to
           rebase instead of merge (see "branch.<name>.rebase"). When never,
           rebase is never automatically set to true. When local, rebase is
           set to true for tracked branches of other local branches. When
           remote, rebase is set to true for tracked branches of
           remote-tracking branches. When always, rebase will be set to true
           for all tracking branches. See "branch.autosetupmerge" for
           on how to set up a branch to track another branch. This option
           defaults to never.

rebase onto a feature/bugfix/hotfix branch from the branch it was branched
from. It should be:

git checkout feature/add-checksum-option
git rebase develop

The new commits from develop will be replayed on the common ancestor and
the feature branch commits will be replayed on top of the new develop
commits, as if the new commits done on develop had been done before instead
of concurrently with the feature branch commits.
