Where it goes
Is LibrarianLib required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does librarianlib-5.0.0-neoforge need?

About this project
What does LibrarianLib add?
LibarianLib offers a large collection of powerful features for modders.
- Facade, a powerful and extremely flexible GUI framework.
- Glitter, high-performance particle systems that can handle tens of thousands of particles.
- Albedo, non-opinionated shader infrastructure. Easily use custom vertex layouts with type-safe but familiar APIs.
- Scribe, automatic annotation-based serialization with full support for generics (e.g.
Map<Identifier, List<Pair<String, Block>>>). - Courier, an easy-to-use networking helper using Scribe.
- Mosaic, data-driven sprite sheets, designed to keep magic constants out of your GUI code.
Note: LibrarianLib for 1.12 uses the Forge mod loader and requires Shadowfacts' Forgelin. The LibrarianLib alpha for 1.17 uses the Fabric mod loader and requires Fabric Language Kotlin.
