+## Graphics
+
+### OpenGL2 (Legacy)
+
+> [!NOTE]
+> As SPIRV to GLSL 120 translation doesn't work, your'e forced to write separate shaders for this backend
+
+### OpenGL3+ (Modern OpenGL)
+
+### DirectX9 (Could potentially cover more than OpenGL2)
+
+### Citro3D (3DS)
+
+> [!NOTE]
+> This backend requires shaders as binary file, directly in the code or as string for libpicasso
+> The Fragment Stage is special and is still wip
