Editing Documentation and help

=Documentation=

* The definitive source of information on LuaTeX is the [http://www.luatex.org/svn/trunk/manual/luatex.pdf LuaTeX Reference]; the link points to the latest version, documenting latest builds, but can be used for older versions too.

* The previous document reduced to a cheatsheet is also available with the [http://www.luatex.org/svn/trunk/manual/old/functionref.pdf Short Reference].

* Besides general information, the [http://www.luatex.org/ LuaTeX site] also hosts [http://www.luatex.org/documentation.html some presentations] by members of the team.

* [http://tug.org/TUGboat/ TUGboat] (communications of the TeX User Group) has featured regular articles on LuaTeX for some years now.

* More can be found in publications by local user groups and conferences.

=Help=

* The [http://tug.org/mailman/listinfo/luatex LuaTeX mailing list] is frequented by knowledgeable people and questions rarely remain unanswered.

* There is also a [http://www.ntg.nl/mailman/listinfo/dev-luatex list for developpers] for very technical things.

* Questions about LuaTeX can also be asked in other TeX-related lists or sites: [http://tug.org/mailman/listinfo/texhax texhax], [http://groups.google.com/group/comp.text.tex comp.text.tex] (and similar groups for different languages), or [http://tex.stackexchange.com/ TeX StackExchange].

=On Lua=

* The main source on the Lua language is the [http://www.lua.org/manual/5.2/manual.html Lua reference manual]; the link here documents version 5.2, currently used by LuaTeX, but Lua 5.1 is what LuaTeX used up to v0.74; see the [http://www.lua.org/manual/5.1/manual.html Lua 5.1 reference manual] if necessary. See also the [http://www.lua.org/manual/5.2/readme.html#changes changes] and [http://www.lua.org/manual/5.2/manual.html#8 incompatibilities].

* [http://www.lua.org/pil/index.html Programming in Lua], by Lua's chief architect Roberto Ierusalimschy, is available online for version 5.0, quite usable for later versions.

* There is also a [http://www.lua.org/lua-l.html mailing list] and a [http://forum.luahub.com/ forum].

* All this and more can be found on the [http://www.lua.org/ Lua website].
