checkout orphan branch

gistfile1.txt

You can do that with a few git commands. Please back up your repo before doing this:

First create the new history:

`git checkout --orphan new-master`

Then create the first commit:

`git commit`

Then delete the old master branch and any other branches you want to delete:

`git branch -D master`

Now you can rename new-master to master:

```
git checkout -b master
git branch -d new-master
```

And now you can force push this new branch to GitHub to make GitHub forget the old history as well:

`git push -u -f origin master`
