+# Josh Graphics Library
+
+# Goals
+* Provide single-function-calls to render various graphics primitives in 2D and 3D.
+* Integrated directly with our other toolkits (ReWindow, J3ML)
+* Quick Rendering of Debug Text, Geometric Widgets, Textures, and so forth.
+
+# Non-Goals
+* Full Rendering Engine
+* OpenGL/Vulkan Wrapper
+* Asset Loading & Management
