You're probably looking for the Sliflist website website to check out rolls and learn more about how we come up with this stuff. GitHub is more for the development side of things.
"I have an idea for a roll!"
That would be awesome, thank you! We've got you covered on the website.
"I'd like to enhance the generator"
Perfect. You're in the right place... except not yet; need to update this section of the docs :)
