adding users and repos

Do NOT add repos or users directly on the server! You MUST manage the server by cloning the special 'gitolite-admin' repo on your workstation (git clone git@server:gitolite-admin), making changes, and pushing them. This section tells you how to add users and repos.

ask each user who will get access to send you a public key. See other sources (for example here) for how to do this
rename each public key according to the user's name, with a .pub extension, like sitaram.pub or john-smith.pub. You can also use periods and underscores
copy all these *.pub files to keydir in your gitolite-admin repo clone. You can also organise them into various subdirectories of keydir if you wish, since the entire tree is searched.
edit the config file (conf/gitolite.conf in your admin repo clone). See the gitolite.conf documentation for details on what goes in that file, syntax, etc. Just add new repos as needed, and add new users and give them permissions as required. The users names should be exactly the same as their keyfile names, but without the .pub extension
when done, commit your changes and push. Any new repos you specified will automatically be created (empty, but clonable) and users' access will be updated as needed.
