+=====
+
+This folder exists to store VLKX renderer objects that are TEMPORARY.
+It currently contains:
+
+=====
+
+Model Loader system
+
+The Model Loader is temporarily implemented as a raw file reader and OBJ parser.
+It should be removed when the File Format system is able to parse model and texture files.
+
+====
+
+Model Abstraction system
+
+The Model Abstraction allows you to create a model with:
+ - A mesh
+ - An arbitrary number of textures
+ - A push constant
+ - An arbitrarily large uniform buffer
+ - A fragment and vertex shader
+
+In all, it contains a custom Render Pipeline that will be used to draw the model.
+This allows for drastic and visually appealing effects.
+
+It should be maintained and moved into the appropriate Shadow module once ready.
+
+====
+
+Model Builder system
+
+The model Builder allows for simple construction of Models using the Model Abstraction system above.
+It consumes the Model Loader and returns a Model Abstraction.
+
+It should be MOVED into the File Format parsing system once it is ready.
