Tips

Keeping your fork up-to-date

(see: Fork a Repo)

Forking a repo on github is pretty easy, there's a button for that. However they do not provide a UI for keeping your fork up-to-date with the parent (upstream) repository.

To keep your fork up-to-date, you'll need to act as an intermediary, shuttling the updates from the upstream repo to your fork. This is handled through git's fetch, merge, push, and remote features.# assumes you have already created a fork of a repo

# assumes you have already created a fork of a repo

# create a clone of the fork specified by "forkURL" and call it forkedRepo
git clone "forkURL" forkedRepo

# set a remote for the upstream repository
git remote add upstream "upstreamURL"

# retrieve the updates from the upstream repository
git fetch upstream

# make sure that you know what you're getting from upstream and what is in your master
git log upstream/master ^master
git log ^upstream/master master

# if everything is good, you can merge upstream into your clone
git merge upstream/master

# now you're ready to update your fork
git push origin master
