Leafpub is Free Software
There's “free” as in freedom and “free” as in beer, and while I very much appreciate both of those things, it's important to remember that even though software may be free, it takes a lot of time and money to develop, maintain, and support.
I'm a lone developer, who works in his spare time on Leafpub, so I can't spend all my time providing free support for Leafpub. If you need help, first check the docs. If you can't find an answer there, please ask your question on the Github issues page so we can all benefit.
Join our dev chat on Gitter. It's a smart way to ask questions or discuss everything and anything.
