+====== DED reference guide ======
+DED (//Doomsday Engine Definition//) is the name of the textual definition language of Doomsday 1.x. One [[#Syntax|syntax]] to define everything from [[ded:generator|Particle Generators]] to [[ded:Thing]]s, in an easy to edit [[http://en.wikipedia.org/wiki/Plain_text|plain text]] format.
+Files in this format are conventionally given the .DED file name extension.
+===== Introduction =====
+This article provides a high level overview of the definition language, including the most important elements in a //.ded// file — the [[#Definition_types|definition types]] themselves.
+Typically a //.ded// file consists of a collection of definitions, either loosely related, or, grouped together according to some organizational structure (usually decided by the mod author).
+Note that the order of the definitions in the //.ded// file affects how Doomsday uses them.
+==== Syntax ====
+All definition files share a single [[ded:syntax|common syntax]] in Doomsday. Once learned, the same knowledge can be applied across the board to all [[#Definition_types|definition types]].
+If you are new to Doomsday modding you'll want to familiarize yourself with [[ded:syntax|DED syntax]] before going further. (It won't take long as its fairly standard/straightforward).
