How to keep up to date a forked repo

Clone the repo first

  $ git clone <url>

Check the remote origin

  $ git remote -v

Add a new upstream

• upstream mean where you get the update from

  $ git remote add upstream <upstream link>

Check the new upstream

  $ git remote -v

For update origin with changes that happened in upstream

• or pull down all the remote changes from upstream
• they are not merge with our local changes

  $ git fetch upstream

For merge with local file

  $ git merge upstream/dev
