- 1Install Forge for the Minecraft version you want Light Overlay on. It counts 5 features across 32 versions. A profile on another version never starts Light Overlay. Forge, Fabric and NeoForge each work for Light Overlay, one at a time.
- 2Put architectury-api and cloth-config in first: Light Overlay will not load without. Architectury-api carries its own version numbers, match them to Light Overlay. 2 files go in before Light Overlay. Architectury-api is not optional for Light Overlay.
- 3Drop light-overlay-13.0.0.jar into the mods folder. The jar goes in whole, Light Overlay unpacks nothing. The folder may hold other mods beside Light Overlay. Only your own client needs Light Overlay.
- 4Start the game and look for Light Overlay in the mods list. It shows nothing on a server list, it is client side. A missing architectury-api keeps Light Overlay out too. No Light Overlay entry means the loader or the version is off.
Light Overlay runs on 32 game versions, 1.13.2 to 1.21.10. Each Light Overlay jar is built per version. 26.2 is 5 releases past Light Overlay. It lists 32 game versions.
