+### Compare changes
+
+In the git-novice lesson we learnt how to diff between commits
+on the same branch.
+You can also look at diffs between branches even if they are on
+a different fork using GitHub.
+
+To see a difference for a repository add `/compare`
+to the end of the repository url.
+
+1. Navigate to: [`https://github.com/MetOffice/git-training-demo/compare/`](https://github.com/MetOffice/git-training-demo/compare/),
+and click on the **compare across forks** link.
+2. Click on the **head repository** dropdown and find your fork.
+3. Click on the **compare** dropdown and select your feature branch.
+
+A diff should appear comparing your fork's feature branch with
+the upstream repositories `main` branch.
