# Synchronize your fork  Remember, we have to regularly update our own copy of the code. Add the `upstream` address (original/protected repository) ```bash $ git remote add upstream git@github.com:LCSB-BioCore/basic-git-practice.git ```  Note the change in the URL. You can then check whether the remote address is set correctly ```bash $ git remote -v ``` <div class="fragment"> Fetch the changes from upstream (similar to pull) ```bash $ git fetch upstream ``` Merge the retrieved changes on the `master` branch: ```bash $ git checkout master $ git merge upstream/master $ git push origin master ``` <div class="fragment"> Do the same for the `develop` branch. <img src="slides/img/icon-live-demo.png" height="100px">
