📢 Important Note Regarding Source Code & File Sizes

⚠️ Why are there only .mrpack files and no extracted source folders or CurseForge .zip files here?

1. GitHub Upload Limit: I wasn't able to upload the raw source code folders or the CurseForge .zip packages directly here because their file sizes exceed the maximum upload limit that GitHub's web interface can handle.
2. Why not CurseForge mirrors? If you are wondering why I didn't just upload the CurseForge version instead—it faces the exact same issue; its size exceeds the limits too!

The Solution: To keep this repository organized and fully working, I have provided the .mrpack files inside the version folders. Inside each folder, I've added a quick guide on how you can easily convert the .mrpack into a .zip using an online tool to get 100% of the configs and source code instantly!
