Keeping a fork up to date

KeepForkUpdate.md

1. Clone your fork:

git clone [email protected]:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream

3. Updating your fork from original repo to keep up with their changes:

git pull upstream master

Clean up a fork and restart it from the upstream
The simplest solution would be (using 'upstream' as the remote name referencing the original repo forked):

  git remote add upstream /url/to/original/repo
  git fetch upstream
  git checkout master
  git reset --hard upstream/master  
  git push origin master --force
