Where it goes
Is Light Level Simple required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.

What else does Light Level Simple v1 need?
Light Level Simple v1. Change the file and its required mods may change too.
Install Architectury API, Cloth Config API (Fabric/Forge/NeoForge) first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
