Syncing a fork

Sync a fork of a repository to keep it up-to-date with the upstream repository.
Before you can sync your fork with an upstream repository, you must [configure a remote that points to the upstream repository](https://help.github.com/articles/configuring-a-remote-for-a-fork) in Git. 1. Open Terminal. 2. Change the current working directory to your local project. 3. Fetch the branches and their respective commits from the upstream repository. Commits to`master` will be stored in a local branch, `upstream/master`.
git fetch upstream
remote: Counting objects: 75, done.
remote: Compressing objects: 100% (53/53), done.
remote: Total 62 (delta 27), reused 44 (delta 9)
Unpacking objects: 100% (62/62), done.

 * [new branch]      master     -> upstream/master
4. Check out your fork's local `master` branch.
git checkout master
Switched to branch 'master'
5. Merge the changes from `upstream/master` into your local `master` branch. This brings your fork's `master` branch into sync with the upstream repository, without losing your local changes.
git merge upstream/master

 README                    |    9 -------
 README.md                 |    7 ++++++
 2 files changed, 7 insertions(+), 9 deletions(-)
 delete mode 100644 README
 create mode 100644 README.md
If your local branch didn't have any unique commits, Git will instead perform a "fast-forward":
git merge upstream/master
Updating 34e91da..16c56ad

6. Pushing to a remote
Use `git push` to push commits made on your local branch to a remote repository.
The `git push` command takes two arguments: * A remote name, for example, `origin` * A branch name, for example, `master`
