I’ve been using it quite successfully in a large OpenResty project.

While you’re right that there aren’t any docs on working with any of the 3rd party projects listed in the homepage - I found that it was pretty straight forward to use as a drop in Lua replacement by examining the compiled Lua from the online REPL. I was surprised how clean the Lua output is. There is really no magic here. I believe one of the project goals is to stay as close to Lua semantics as possible. Basically just lisp flavored Lua.

In my project I just use the compiled .fnl files as I would any of other .lua file.

Is something specific you’re getting stuck with? I’d be happy to try to point you in the right direction.

It’s really nice! I encourage you to give it another try.
