If you don't know what's Homu or why you should use it check http://homu.io/
The issue with homu.io

And the alternative is to roll your own Homu instance and use that with your repositories. So I wrote this Heroku app that configures and launches a Homu instance; and that you can also deploy and run at zero cost.
Deploying the Heroku app is nowhere as simple as registering on homu.io so the README in that repository documents all the required steps. On the bright side, you get to name and own a Homu bot.

That's it. If you encounter any issue (or typo) while following the guide let me know and I'll help.
