Essential standard libraries for the Quilt ecosystem. QSL gives modders Quilt-exclusive tools to add new and exciting features to their mods, while Quilted Fabric API provides compatibility with Fabric mods that use the Fabric API.

Notes
Quilt is currently still in development, and in beta.
This means issues may arise but we will do our best to fix them as fast as we can. Quilted Fabric API does not support the "implementation details" of most of Fabric API.
Mods that use implementation details may work on Fabric, but will not work on Quilt.
