+Applying a Patch to Git

 Scenario:
 
-- A Mercurial patch exists but there is no pull request for it.
+- A patch exists but there is no pull request for it.
 
 Solution:
 
 1. Download the patch locally.
 
 2. Apply the patch::
 
-       git apply /path/to/issueNNNN-git.patch
+       git apply /path/to/patch.diff
 
    If there are errors, update to a revision from when the patch was
    created and then try the ``git apply`` again:
 
    .. code-block:: bash
 
        git checkout $(git rev-list -n 1 --before="yyyy-mm-dd hh:mm:ss" main)
-       git apply /path/to/issueNNNN-git.patch
+       git apply /path/to/patch.diff
 
    If the patch still won't apply, then a patch tool will not be able to
    apply the patch and it will need to be re-implemented manually.
