[Gitolite](https://github.com/sitaramc/gitolite) is a git repository manager. Here's how to add git-annex support to gitolite, so you can `git annex copy` files to a gitolite repository, and `git annex get` files from it. A nice feature of using gitolite with git-annex is that users can be given read-only access to a repository, and this allows them to `git annex get` file contents, but not change anything. First, you need new enough versions: * gitolite 2.2 is needed -- this version contains a git-annex-shell ADC and supports "ua" ADCs. Alternatively, gitoline g3 also recently added support for git-annex. * git-annex 3.20111016 or newer needs to be installed on the gitolite server. Don't install an older version, it wouldn't be secure! And here's how to set it up. The examples are for gitolite as installed on Debian with apt-get, but the changes described can be made to any gitolite installation, just with different paths. Set `$GL_ADC_PATH` in `.gitolite.rc`, if you have not already done so.
echo '$GL_ADC_PATH = "/usr/local/lib/gitolite/adc/";' >>~gitolite/.gitolite.rc
Make the ADC directory, and a "ua" subdirectory.
   
mkdir -p /usr/local/lib/gitolite/adc/ua
Install the git-annex-shell ADC into the "ua" subdirectory from the gitolie repository.
   
cd /usr/local/lib/gitolite/adc/ua/
cp gitolite/contrib/adc/git-annex-shell .
If using gitolite g3, an additional setup step is needed: In the ENABLE list in the rc file, add an entry like this:
	'git-annex-shell ua',
Now all gitolite repositories can be used with git-annex just as any ssh remote normally would be used. For example:
# git clone gitolite@localhost:testing

### Troubleshooting I got an error like this when setting up gitolite *after* setting up a local git repo and git annex:
git-annex-shell: First run: git-annex init
Command ssh ["git@git.example.com","git-annex-shell 'configlist' '/~/myrepo.git'"] failed; exit code 1
because I forgot to "git push --all" after adding the new gitolite remote.
