Git
Slightly modified answer from “Make the current commit the only (initial) commit in a Git repository” on Stack Overflow:
git checkout --orphan newBranch
git add --all # Add all files and commit them
git commit --message="Initial commit."
git branch --delete --force master # Deletes the master branch
git branch --move master # Rename the current branch to master
git push --force --set-upstream origin master # Force push master branch to github
git gc --aggressive --prune=all # remove the old files
