# Firefrost Rules Mod — Build Environment

## Project Structure
- `1.21.1/` — NeoForge (Java 21, Gradle 8.8, moddev 2.0.141)
- `1.20.1/` — Forge (Java 17, Gradle 8.8, ForgeGradle 6.0)
- `1.16.5/` — Forge (Java 8, Gradle 7.6.4, ForgeGradle 5.1)

## 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 at `config/firefrostrules-common.toml` (COMMON type).
Changed from SERVER to COMMON in v1.0.2 to fix config reset on restart.
See `INSTALL.md` for full install steps.
