I've been asked about deploying Taskotron for a dev instance on multiple occasions and I just pushed some playbooks and support files that will make doing this much easier.
I would like to re-iterate that most people won't need this. libtaskotron is designed to work standalone - you do not need an entire deployment to work on tasks. The only time you might need a complete dev instance is if you're working on the support bits that interact with eachother or want to demo the system as a whole.
That being said, the setup is still a bit user-unfriendly. The readme should cover all the stuff needed for setup but let me know if something's missing:
