Welcome to the Lapis reference manual. You can find a list of all the guides to the left. Because Lapis is a hybrid framework for both Lua and MoonScript you can toggle language of the examples in the documentation from the sidebar. Some guides only apply to a certain language.
If you're not sure what Lapis is you can find a general overview on the homepage: http://leafo.net/lapis.
Lapis is open source, you can find the souce code here: http://github.com/leafo/lapis.
If you are having any problems with Lapis open an issue on the issues tracker.
Looking to see some projects using Lapis?
Thanks and enjoy Lapis!
