+      Use the ``SPHINX_JOBS`` ``make`` variable (defaults to ``auto``)
+      to specify an explicit amount, e.g. ``make build SPHINX_JOBS=10``.

       It may fail the build because there may be files
       that don't exist anymore in the new branch.
       If that's the case, just continue with the steps
