 checks out the latest version of your project from the current branch and
 runs the following callback scripts:
 
+* `deploy/setup` - on first push.
 * `deploy/after_push` - on subsequent pushes. It in turn executes:
   * `deploy/before_restart`
   * `deploy/restart`
   * `deploy/after_restart`
+* `deploy/rollback` - executed for `git deploy rollback`.
 
 All of the callbacks are optional. These scripts are ordinary Unix executables.
 The ones which get generated for you by `git deploy init` are written in shell
 script and Ruby.
