Always use repos URLs of form git@iscm:reponame
(with an exception for from-client installation method).

The special Admin user "gitadm" works with the special gitolite-admin
repository by cloning it remotely, working with it, and pushing changes back.

List repositories with:  ssh -T ownerShell@reposHost

Main server-side config file is ~git/.gitolite.rc.

ADD REPOSES
    If you already have content in some git repos (like standalone), instead of
     adding the content later, you can
     copy the bare repository to a subdir of ~git/repositories on the server
     before doing the steps below.  Make sure the repos home names end in .git.
    CHECK OUT gitolite-admin repository then...
    Edit gitolite-admin/conf/gitolite.conf, using "example.conf" from the
     gitolite source repos as example.
    (Omit the ".git" suffix from repository names).
    Assign users privs in the repository.
    Commit and push.
    Repos will be created empty (unless you created it on the server above).
    Populate empty repos exactly same as you would any empty remote repos.

ADD USERS
    Copy pub keys to local gitolite-admin/keydir/...<USER>.pub.
    (I.e. in keydir or any subdirectory for categorical purposes).
    Periods and underscores ok.
    Edit gitolite-admin/conf/gitolite.conf and assign repository privs.
    Commit and push.

Awesome help (like when service configs get out of whack):
