 Git has two ways to update your branch with the newest changes: merging and rebasing.
 Rust [uses rebasing][no-merge-policy]. If you make a merge commit, it's not too hard to fix:
-`git rebase -i origin/master`.
+`git rebase -i upstream/master`.

+### Git is trying to rebase commits I didn't write?
+
+If you see many commits in your rebase list, or merge commits, or commits by other people that you
+didn't write, it likely means you're trying to rebase over the wrong branch. For example, you may
+have a `rust-lang/rust` remote `upstream`, but ran `git rebase origin/master` instead of `git rebase
+upstream/master`. The fix is to abort the rebase and use the correct branch instead:
+
+```
+git rebase --abort
+git rebase -i upstream/master
