 # WiiPy
-A simple CLI tool that serves as a reference implementation of libWiiPy.
+WiiPy is a simple command line tool to use [libWiiPy](https://github.com/NinjaCheetah/libWiiPy)'s features to manage file formats used on the Wii. WiiPy also serves as a relatively simple reference implementation for libWiiPy's features, as it's designed to utilize all of them.
+
+WiiPy is cross-platform, and supports macOS, Windows, and Linux, both because it's written in pure Python, and because it can be compiled for all three platforms via Nuitka.
+
+To see what features are supported, I would recommend checking out the list of features that libWiiPy offers, which can be found [here]("https://github.com/NinjaCheetah/libWiiPy?tab=readme-ov-file#features").
+
+## Requirements
+libWiiPy has been tested on both Python 3.11 and 3.12, and works as expected in both places. libWiiPy *should* support Python 3.10, however this is not verified. WiiPy only relies on libWiiPy, so it supports the same Python versions.
+
+To make sure you have libWiiPy and all of its dependencies, you can simply run:
+```shell
+pip install -r requirements.txt
+```
+
+## Usage
+Basic usage for WiiPy is very simple.
+```shell
+python3 wiipy.py <subcommand>
+```
+You can use `--help` to see a list of all subcommands, or use `<subcommand> --help` to see usage instructions for that subcommand.
+
+Available subcommands will expand as support for more features are added into libWiiPy. WiiPy is designed around libWiiPy's `main` branch, so any features that have been merged into main are likely to be supported here within a short period of time. This also means that any breaking changes to the library will be handled here quickly, so incompatibilities shouldn't happen.
+
+## Compiling
+If you'd like to compile WiiPy from Python into something a little more native, you can use one of the following commands. Make sure you've installed Nuitka first (it's included in `requirements.txt`).
+```shell
+python -m nuitka --show-progress --assume-yes-for-downloads --onefile wiipy.py
+```
+On macOS and Linux, this will give you a binary named `wiipy.bin` in the same directory as the Python file. On Windows, you'll get a binary named `wiipy.exe` instead.
