git pull upstream branch code example

Example 1: git fetch upstream

These steps update the master branch.

	git fetch upstream

3. Merge upstream with the appropriate local branch

4. Get help on Resolve merge conflicts if these occur.

5. If you also maintain a GitHub repository, push changes to 
	GitHub’s (origin) master branch
	git push origin master
