 ## Presentation
 
 This is a pure Lua (+ LPEG) implementation of Datalog.
 
-The core interpreter (`datalog/datalog.lua`) is a modified version of
-[John D. Ramsdell's Datalog](http://datalog.sourceforge.net/) from the
-MITRE corporation.
-
-This is a work in progress, don't expect it to work flawlessly.
+The core interpreter (`datalog/datalog.lua`) is a modified version of [John D. Ramsdell's Datalog](http://datalog.sourceforge.net/) from the MITRE corporation.
 
 ## Usage
 
     lua main.lua examples/path.dl
 
 ## Dependencies
 
-This is currently only tested with Lua 5.3 compiled with backwards
-compatibility for 5.1 and 5.2 and LPEG 0.12. It probably works fine with
-other Luas though.
+PUC Lua 5.1 or above + LPEG. This is not tested with LuaJIT (but it probably works).
 
 Tests depend on [cwtest](https://github.com/catwell/cwtest).
