get changes from forked repo code example

Example 1: update fork repository

## Add Original Repository
git remote add upstream https://github.com/OriginalOwner/OriginalProject.git

## Verify if Repository is added
git remote -v

## Fetch Updates from Original Repository
git fetch upstream

## Checkout to your master branch
git checkout master

## Get Updates from upstream repo
git merge upstream/master

## Push the commit over 
git push origin master

Example 2: git pull updates from fork

$ cd github-services
$ git remote add upstream git://github.com/pjhyett/github-services.git
$ git fetch upstream

# then: (like "git pull" which is fetch + merge)
$ git merge upstream/master master

# or, better, replay your local work on top of the fetched branch
# like a "git pull --rebase"
$ git rebase upstream/master
