Just head over to the GitHub page and click the "Fork" button. It's just that simple. Once you've done that, you can use your favorite git client to clone your repo or just head straight to the command line:
git clone https://github.com/USER_NAME/JIT-Hack.git
Keeping Your Fork Up to Date While this isn't a necessary step, if you plan on doing anything more than a tiny quick fix, you'll want to make sure you keep your fork up to date by tracking the original "upstream" repo that you forked earlier. To do this, you'll need to add a remote:
git remote add upstream https://github.com/techclubjit/JIT-Hack.git
("JIT-Hack" is used as the example repo. Be sure to reference the actual repo you're contributing to e.g. "JIT-Hack").
git remote -v
Whenever you want to update your fork with the latest upstream changes, you'll need to first fetch the upstream repo's branches and latest commits to bring them into your repository:
git fetch upstream
git branch -va
Now, checkout your master branch and merge the upstream repo's master branch:
git checkout master
git merge upstream/master
If there are no unique commits on the local master branch, git will simply perform a fast-forward. However, if you have been making changes on master (in the vast majority of cases you probably shouldn't be - see the next section, you may have to deal with conflicts. When doing so, be careful to respect the changes made upstream.
Now, your local master branch is up-to-date with everything modified upstream.
Create a Branch (doing your work) Whenever you begin work on a new feature or bugfix, it's important that you create a new branch. Not only is it proper git workflow, but it also keeps your changes organized and separated from the master branch so that you can easily submit and manage multiple pull requests for every task you complete.
To create a new branch and start working on it, perform the following flow.
git checkout master
For enhancements use feature/your_username/issue# or feature/your_username/name_of_feature
For bugs use bug/your_username/issue# or bug/your_username/name_of_bug
git branch feature/techclubjit/567
git checkout feature/techclubjit/567
Now, go to town hacking away and making whatever changes you want to.
Before submitting your pull request, you might want to do a few things to clean up your branch and make it as simple as possible for the original repo's maintainer to test, accept, and merge your work.
In the time that you've been working on your changes, if any commits have been made to the upstream master branch, you will need to rebase your development branch so that merging it will be a simple fast-forward that won't require any conflict resolution work.
git fetch upstream
git checkout master
git merge upstream/master
git checkout feature/techclubjit/1
git rebase master
Now, it may be desirable to squash some of your smaller commits down into a small number of larger more cohesive commits. You can do this with an interactive rebase:
git checkout
git rebase -i master
This will open up a text editor where you can specify which commits to squash.
Once you've committed and pushed all of your changes to GitHub, go to the page for your fork on GitHub, select your development branch, and click the pull request button. If you need to make any adjustments to your pull request, just push the updates to GitHub. Your pull request will automatically track the changes in your development branch and update it.
