 This is a tool written with node.js to keep a directory up to date and checked out with the current versions on the remote server.
 
-This documentation is unfinished, the project doesn't even have any code written yet, so bug me to fix it later.
+You must create a `config.json` with at least a `repo` which points to a git repo, and a `title` which is used in the display.  You may also change the output directory with `output` and the repo working area with `working`.
+
+At that point, if you `grunt` it should clone the remote repo and start setting up a folder for each brach and tag.
+
+If you create a file called `build-command.sh` it will be executed in the directory for each branch and tag after it is updated.
+
+A `cron.sh` is provided to run `grunt cron` and surround it in a `.lock` check.
