-## 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
 
 ## Features
 
 * Modern C++ (20)
-* Little-to-no overhead
-* No hand-holding
-* No-frills, straight up just renders shapes and text.
+* Provides single-function-calls to render various graphics primitives in 2D and 3D.
+* Integrates directly with our other toolkits (ReWindow, J3ML)
+* Quick Rendering of Debug Text, Geometric Widgets, Textures, and so forth.
+* Little-to-no overhead.
 * Integrates right into an existing OpenGL rendering system.
+* High-performance text rendering.
+
+## API Overview
+
+### J2D
+* DrawPixel
+* DrawLine / DrawGradientLine
+* DrawSprite
+* OutlineRect / FillRect / FillGradientRect / FillRoundedRect
+* OutlineCircle / FillCircle
+* OutlineTriangle / FillTriangle
+* DrawString
+### J3D
+* DrawLine
+* DrawString
+* DrawMatrixGizmo (WIP)
+* DrawAxisAngleGizmo (WIP)
+* DrawQuaternionGizmo (WIP)
+
+### Types
+* Font
