-### `--changedFilesToContributeTo`
-
-When used together with `--onlyChanged` or `--watch`, it runs tests related the
-changes since the provided revision. If the current branch is not a child of the
-given commit, then only changes made locally will be tested.

 ### `--changedFilesWithAncestor`
 
 Runs tests related to the current changes and the changes made in the last
 commit. Behaves similarly to `--onlyChanged`.

+Runs tests related the changes since the provided branch. If the current branch
+has diverged from the given branch, then only changes made locally will be
