 About QuakeC
 ------------
 
 QuakeC is a very simplified dialect of the well-known C programming language, and is used by the Quake I engine and its derivatives. Xonotic uses the GMQCC dialect of QuakeC, so only this dialect will be described (as well as some common extensions among Quake engines).
 
+There are several documents describing the original version of QC as used in Quake 1:
+- an [old version](http://www.gamers.org/dEngine/quake/spec/quake-spec34/index1.htm) which is a part of unofficial [Quake Documentation](http://www.gamers.org/dEngine/quake/spec/quake-spec34/)
+- a probably slightly [newer version](http://www.cataboligne.org/extra/qcmanual.html)
+- a [newer and extended version](http://pages.cs.wisc.edu/~jeremyp/quake/quakec/quakec.pdf) in PDF
+
+Even this page is outdated and incomplete, not all GMQCC QuakeC constructs are described here and some of the bugs mentioned here have already been fixed.

 **Note:** *findchain* is implemented in QuakeC for demonstration purposes only so one can see how to build a linked list, as this function is already built in to the engine and can be used directly
