How to reset a remote GIT repository to remove all revisions?

Question

How to reset a remote and local GIT repository to remove all revisions, and start fresh with the current Head as initial commit.

Answer 1

First, follow the instructions in this question to squash everything to a single commit. Then make a forced push to the remote:

$ git push origin +master

And optionally delete all other branches both locally and remotely:

$ git push origin :<branch>
$ git branch -d <branch>

Answer 2

Completely reset?

1) Delete the .git directory locally. 2) Recreate the git repostory

$ cd (project-directory)
$ git init
$ (add some files)
$ git add .
$ git commit -m 'Initial commit'

3) Push to remote server, overwriting. Remember you're going to mess everyone else up doing this... you better be the only client.
