+# godot-wii-u
+WIP port of Godot 4 to Wii U
+
+Uses Wii U Toolchain.
+
+This repo will only contain the relevant folders to add to an existing copy of the Godot source code.

+# Compiling
+
+I'm adding this here just so people don't ask about it. The SCons script to build the platform isn't done, nor will I worry about it until I have enough done to make it work trying to compile to see if it works.
+
+If you have any questions, join [The Homebrodot Discord](https://discord.gg/mYzXDke5yv),[my Discord](https://discord.com/invite/Mu6YUEmerN) or make an issue here on GitHub.
