The Git versioning system allows you to manage large-scale distributed code development projects with thousands of parallel branches. Its powerful checkout, merge, push, and pull capabilities help you work with code branches and clones. Sometimes you, as a contributor, might like to polish a branch you’ve checked out and reduce the number of commits you made before merging it with the master branch. One of Git’s nicer features is that it lets you rewrite history.
Rewriting history is not about changing the end result, but about making things cleaner and clearer. For instance, you can remove commits from the times when you added and later removed debug outputs, or merge the fixes you made to a feature with the commit that added the actual feature. The overall goal is to simplify history for the person who merges your branch into the master branch.
