 * `test` - The tests that should be run during the build. Plugins run during this phase will contribute to the success or failure of the build.
 
+* `deploy` - The deploy that should be run after the build. Plugins run during this phase will contribute to the success or failure of the build.
+
 * `complete` - Always called when the `test` phase completes, regardless of success or failure. **Note** that is you do any DB stuff here, you will need to add the DB credentials to this section as well, as it runs in a separate instance.
 
 * `success` - Called upon success of the `test` phase.
