+## Introduction
+
+&ensp; The platform support library will include headers, functions, and classes related  
+to supporting various platforms. Platforms may be defined as any Hardware, OS, or  
+Drivers that must be initialized for the engine context.
+
+
+## Implementation
+
+Platform Support will be implemented in the following order:
+- Linux/BSD
+    - Wayland
+        - OpenGL (EGL) ✔
+        - XKB
+        - PulseAudio
+        - Vulkan
+    - X11
+        - ALSA
+        - Vulkan
+- Microsoft Windows
+    - XInput
+    - OpenGL (WGL)
+    - WASAPI
+    - Vulkan
+- Android
+    - OpenGL ES
+    - AAudio
+    - openslES
+- macOS/iOS
+    - cocoa
+        - OpenGL
+        - Core Audio
+        - Vulkan
+        - Metal
+
+&ensp; Linux Wayland will be implemented first. Once setup, the core engine will be   
+implemented and tested on top of Wayland. Once the engine is in a stable state,  
+then support for other platforms will be resumed.
+
+
+## Consoles
+
+&ensp; 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.
