This is fairly quick, but I haven't realised how important it is up to now - a friend made up such a mess of his repository adding and changing files before committing that he wanted to delete the folder and start from scratch.
Is it worth it? Not really, you can move around Git's history with this command:
git reset --hard <SHA of the target commit>
Why do I say it is an important thing to keep in mind? Think of it this way: if the user comes from TFVC, this is equivalent to a local Undo All and to Get Specific Version and Get Latest Version (with HEAD instead of the SHA) commands.
