+    This recipe is **incomplete**, and is featured to align the [patrons](https://www.patreon.com/funkypenguin)'s "premix" repository with the cookbook.  "_premix_" is a private git repository available to [all Patreon patrons](https://www.patreon.com/funkypenguin), which includes necessary docker-compose and env files for all published recipes. This means that patrons can launch any recipe with just a ```git pull``` and a ```docker stack deploy``` 👍
