This note explains how to apply new commits in your forked repo from the parent (upstream) repo. If not already done, add a “remote” to the parent’s repo like this :
git remote add parent https://github.com/project/name.git
Then, fetch all commits from the parent’s branch master (or any branch you like) :
git fetch parent master
Now, apply all new commits to your repo :
git rebase parent/master
You may have conflicts to solve if you’ve done modifications on your repo. Solve them before going on.
Finally, push (and force) all your modifications :
git push --force origin master
