 This is the ''most basic'' introduction to setting up CEGUI to render. There are things not covered here, such as using different scene managers in Ogre and advanced options such as user specified resource providers, and so on.

 In order to get CEGUI to render, no matter what your target engine is, there are basically three steps that must be done.

 Obviously you also need to load some data and perform very basic initialisation, which is covered in [[The Beginner Guide to Loading Data Files and Initialisation]], and also you need to get your inputs into the system which is covered in [[The Beginner Guide to Injecting Inputs]].

 === Create an instance of a CEGUI::Renderer based object ===
-This is fairly straight forward and should pose no major obstacles for any of the supported renderers.  You must of course remember to include the header file for the renderer that you will be using, also remember that for Ogre3D the renderer module now comes with CEGUI and not Ogre (Huh? Since when? As of 23/02/2010 (CEGUI 0.7.1, OGRE 1.7) the module is called CEGUIOgreRenderer, and is in CEGUI's sources, not Ogre's). (Note that you need to delete the Renderer object when you are cleaning up the program.)
