+## What are Games and Mods?
+
+The power of Minetest is the ability to easily create games without the need
+to write your own voxel graphics and algorithms or fancy networking.
+
+In Minetest, a Game is a collection of modules which work together to provide the
+content and behaviour of your game.
+A module, commonly known as a mod, is a collection of scripts and resources.
+It's possible to make a Game using only one mod, but this is rarely done and makes things
+infeasible.
+
+It's also possible to distribute mods outside of a game, in which case they
+are also *mods* in the more traditional sense - modifications.
+Both the mods contained in a Game and third-party mods use the exact same API,
+which makes things easier.
+This book will go over the main parts of the Minetest API,
+and is applicable for both game developers and modders.
