Git remove-How do I remove Git tracking from a project?

 I want to remove Git tracking from a project's directory. What is the correct method to do this? Can I do a shell command such as

rm -rf .git

from my projects directory or is there a way to do this as a Git command?

I used this project to learn Git and realize I made some mistakes early on in the project with moved, renamed and deleted files. I'd like to remove all Git tracking and start fresh with git init.
