 ## What This Mod Does
 Player types `/rules` → mod fetches rules from a Discord message → displays in-game with colored formatting. Admins update rules by editing a Discord message — no restarts, no file editing.
 
+## Config Location
+Config file is created at `world/serverconfig/firefrostrules-server.toml` — NOT in `config/`. This applies to all three versions.
