Contents
The book is a comprehensive Doom editing guide. It begins with the utmost basics of map construction by explaining IWADs and PWADs, elements of levels such as vertexes, linedefs, and sectors, and illustrates the basic limitations of Doom's two-dimensional map format.

The bulk of the book, a total of four of nine chapters, is dedicated to in-depth discussion of two of the then most prominent editor utilities. DEU is given two chapters, one on basics and one on advanced techniques, and DoomCAD is likewise covered. Topics include configuration, user interface, basic construction of rooms, and building constructs such as crushing ceilings, windows, doors, and more.

Other topics covered include advice on artistic design, effective use of NWT for manipulating WAD files, and using DeHackEd to edit monsters, weapons, strings, and more.
