 # Dynmap®  - dynamic web maps for Minecraft servers
 
+> **About this fork.** This repository tracks [Dynmap](https://github.com/webbukkit/dynmap)
+> with an added **NeoForge 1.21.1** build. The `main` branch mirrors the upstream
+> multi-platform project (Spigot/Paper, Forge, Fabric, and the original README below);
+> the **`neoforge-1.21.1`** branch holds the standalone NeoForge 1.21.1 port and its own
+> build/install instructions. For the canonical project, see
+> [webbukkit/dynmap](https://github.com/webbukkit/dynmap).
