About this project
What does Cobweb add?

📝 Description
Cobweb is a lightweight, modular API designed to simplify Minecraft mod development across multiple loaders.
It provides a Unified Configuration System and a Unified Registering System, both available directly in the common module. These systems help you abstract away the differences between loaders, so you can focus on writing clean, maintainable, and reusable code — not boilerplate.
Cobweb is the shared modding API used across all Crystal Nest projects.
