a good roadmap to learn lua: https://www.lua.org/pil/ - basic knowledge https://www.lua.org/manual/5.1/manual.html#7 - differences between 5.0 and 5.1; and the whole reference manual itself, you can let the c parts to the end, so like half of the manual (chapter 3 and 4) https://www.lua.org/ - in general, because it's a nice set http://lua-users.org/ - here is a great collection of kinda much anything around lua that you can find in the wild... and of course this mailing list as this made my basic knowledge sharp :D
