Steps to clear out the history of a git/github repository

git-clearHistory

-- Remove the history from 
rm -rf .git

-- recreate the repos from the current content only
git init
git add .
git commit -m "Initial commit"

-- push to the github remote repos ensuring you overwrite history
git remote add origin git@github.com:<YOUR ACCOUNT>/<YOUR REPOS>.git
git push -u --force origin master

Using just a branch isnt a good concept for branching.

Its always depends about how your workflow looks like and then learn how to branch.

worked like charm

Above didn't work but the following worked with more attributes during the push.

git init
git add .
git commit -m 'Initial commit'
git remote add origin [repo_address]
git push --mirror --force

Thanks @heshanlk , the --mirror option was what I needed!

See here, nice script which takes care of it all maintaining the original config which is what you want: resetting github repo
