# Introduction

Documentation is like sex: when it is good, it is very, very good; and when it is bad, it is better than nothing.

GZDoom Builder is a Doom Builder 2 fork, which aims to incorporate as many GZDoom features as possible. Currently it's the only map editor for Doom and games based on Doom engine, which supports 3D models, dynamic lights and colored fog.

## Reference Manual

This is the Reference Manual for GZDoom Builder. You can use this manual to look up how the specific GZDoom Builder features work and what the specific modes and actions do.

This manual is not a beginners tutorial that teaches you how to make maps. To learn the mechanics of how to make maps read Doom Builder: An Illustrated Guide (http://www.doombuilder.com/files/doombuilder1guide.pdf).
