How to update a fork

how-to-update-a-fork

# Clone your fork
```
$ git clone https://github.com/your-username/your-repository-name.git
```

# Create a remote upstream with the original repository
```
$ cd your-repository-name
$ git remote add upstream git://github.com/original-username/repository-name-forked.git
```

# Update your repository
```
$ cd your-repository-name
$ git fetch upstream
$ git pull upstream master
```
I keep a branch as the original where then I check before the merge. So before the git-pull command, I run git-checkout for updating only that branch.
