 Inkay also includes game-specific patches to add extra features:
 - Modpack-specific matchmaking for global, regional rooms (by simulating extra DLC) - **Mario Kart 8**

-## Dependencies
+## Requirements
 Inkay is only supported on the release version of Aroma configured for autoboot/coldboot. Other configurations (specifically lacking coldboot) may cause issues with SpotPass.
 
 ## Safety
 Inkay's patches are all temporary, and only applied in-memory without modifying your console. The SSL patch, while also temporary, could reduce the overall security of your console while active - this is because it no longer checks if a server is verified. However, this does not apply to the Internet Browser, where SSL still works as expected.
 
+## Compiling - Docker
+Inkay's dependencies and build tooling can be handled as a container, which is recommended for WUPS plugins. Using `docker` or `podman`:
+```shell
+docker build -t inkay .
+docker run --rm -v $(pwd):/app inkay make
+# you can replace "make" with other commands - e.g. make clean
+```
+If using `podman` on SELinux systems (like Fedora Linux), you might need to use `$(pwd):/app:Z` instead of `$(pwd):/app`.
+
+## Compiling - System
+Inkay has the following dependencies aside from devkitPPC and wut:
+- [WiiUPluginSystem](https://github.com/wiiu-env/WiiUPluginSystem)
+- [WiiUModuleSystem](https://github.com/wiiu-env/WiiUModuleSystem)
+- [libmocha](https://github.com/wiiu-env/libmocha)
+- [libkernel](https://github.com/wiiu-env/libkernel/)
+- [libnotifications](https://github.com/wiiu-env/libnotifications/)
+- [libfunctionpatcher](https://github.com/wiiu-env/libfunctionpatcher)
+
+Each of these should be `make install`-able. After that, you can compile Inkay with `make`.
