WIP U8 archive info and improved support for matching other files

Info command now displays more info for TMDs, as well as info for Tickets or entire WADs.
EmuNAND command now allows for bulk installing a folder of WADs, and will create/update uid.sys during installation.

 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.
+libWiiPy has been tested on both Python 3.11 and 3.12, and works as expected in both places. WiiPy relies only on libWiiPy, so generally any version supported by libWiiPy should be supported by WiiPy.
 
 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.
+You can use `--help` to see a list of all commands, or use `<command> --help` to see usage instructions for that command. This also applies to subcommands, with the syntax `<command> <subcommand> --help`.
+
+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 updates to the library will be addressed here quickly, so breaking changes in libWiiPy shouldn't cause issues.

 ## 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`).
@@ -28,3 +31,19 @@ If you'd like to compile WiiPy from Python into something a little more native,
 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.
+
+### For Linux Users:
+A Makefile has been included to both build and install WiiPy on Linux. This will install `wiipy` to `/usr/bin/`.
+
+First, use make to build WiiPy (this automates the step above):
+```shell
+make linux
+```
+
+Then, run the install command with `sudo` (or your favorite alternative):
+```shell
+sudo make linux-install
+```
+
+### A Note About Scripts
+WiiPy's source includes a directory named `scripts`, which is currently where miscellaneous libWiiPy-based scripts live. Note that they are not part of WiiPy releases, and are not tested the same way the WiiPy is. They are simply here for those who may find them useful.
