This reference manual is divided in four parts. The Model reference documents the available objects that can be included in a simulation file. The Orchestration reference documents every GeMA function that can be used on the orchestration script (It doesn't includes process functions, since those are documented by the plugin that provides the function). The Plugin reference documents every aspect related with the available plugins. Finally, the Scripts reference documents a set of auxilliary Lua functions available for usage both in the model description and in the orchestration script.

Although no formal knowledge of the Lua language is necessary for creating GeMA simulations, and the GeMA tutorial presents the basic needed concepts on section III, those wanting to became advanced GeMA users can benefit from learning more about the language. GeMA uses Lua version 5.2, and its manual can be found here. Another reference is the Programming in Lua book, by the language authors.
