Reset repo history in Git

After doing a lot of pushed to a repo in github the cloning becomes slower and slower specially if you have images or media files that are generated everytime. Sometimes we don't actually care about the history of the repo, so thats what is this post about, deleting a repo's history. I use this for OnToology testing.

1. Checkout
   git checkout --orphan latest_branch
2. Add all the files
   git add -A
3. Commit the changes
   git commit -am "commit message"
4. Delete the branch
   git branch -D master
5. Rename the current branch to master
   git branch -m master
6. Finally, force update your repository
   git push -f origin master

If you have a better way, please do not hesitate to share it ;)
