A slight change to your recommendation:


OPTIONS
-------
--object-dir::
         Use given directory for the location of packfiles and commit graph
         file. This parameter exists to specify the location of an alternate
         that only has the objects directory, not a full .git directory. The
         commit graph file is expected to be at <dir>/info/commit-graph and
         the packfiles are expected to be in <dir>/pack.
