+	Node to draw simple geometry from code, ala OpenGL 1.x
 	</brief_description>
 	<description>
 	</description>
+	ImmediateGeometry is a node used for displaying simple geometry created from code, very similar to how glBegin() and glEnd() worked in old versions of OpenGL (1.x). 
+	Simply call [method begin()], and add vertices. For custom vertex colors, uvs, normal, etc. call one of the set_ functions below before adding each vertex. When done, call [method end]
+	Calls to begin/end are accumulative and all geometry is added together. To clear all the geometry, call [method clear].
+	If a material override is set, and this material contains a texture, it's possible to override the texture used in this material for every begin/end set of calls.
