+### Platform & API Support
+
+I have decided to forgo SDL, this is so the engine can provide specific support for specific platforms.
+Also, SDL implements a lot of things that will need to be implemented specifically for the engine, so only the window
+management would be used.
+
+Platform support will be implemented in the following order:
+ - Linux/BSD
+   - Wayland
+     - XKB
+     - OpenGL (EGL)
+     - PulseAudio
+     - Vulkan
+   - X11
+     - OpenGL (EGL)
+     - ALSA
+     - Vulkan
+ - Microsoft Windows
+   - XInput
+   - OpenGL
+   - DirectSound
+   - Vulkan
+ - Android
+   - OpenGL ES
+ - macOS
+ - iOS
+
+Most consoles will never get official platform support due to NDAs which conflict with the principles of this engine.
+fennec will avoid using proprietary libraries except when strictly necessary, such as support for Windows and MacOS.
+fennec will interact with any drivers required for the listed operating systems above, even if proprietary.
