Harmony — A Shared Patching Library for RimWorld Mods

Harmony provides a common patching library used by many RimWorld mods. It lets supported mods rely on one shared version instead of bundling separate copies.

Why it is needed

Harmony is a technical dependency for other mods. Installing it supplies the library those mods need to apply their code changes.

For mod authors, this simplifies dependency management and reduces duplicate 0Harmony.dll files across mod folders.

Installation

Install and enable Harmony, then keep it near the top of your active mod list, before mods that depend on it.

Once enabled, dependent mods can use the shared library.
