FTB Library serves as a foundational component for FTB Mods. It's designed to simplify and enhance the modding experience for our developers, streamlining the development process for mods within the Feed the Beast ecosystem. While primarily intended for use by FTB Mods such as FTB Chunks and FTB Quests, it is not explicitly prohibited for integration into non-FTB mods. However, please note that using it in such contexts may pose challenges, and the responsibility for resolving any resulting issues falls upon the mod developer.

Extensible Sidebar Buttons
FTB Library introduces the capability for other mods to create sidebar buttons via JSON files, enhancing the overall functionality and versatility of FTB Mods.

Note: While FTB Library is not designed for use in non-FTB mods, it is not explicitly restricted. Developers choosing to integrate it into such projects should be prepared for potential challenges.
Please proceed with caution and take full responsibility for any compatibility or integration issues that may arise. You can report bugs or feature requests on our GitHub issues page.
