+# lassiter-mudlet — the package Lassiter Creek offers your Mudlet on connect
+
+**Public on purpose.** The game (a MUD, Mudlet only) sends GMCP `Client.GUI` when you log in; Mudlet fetches
+`lassiter-mapper.xml` from here and installs it — a mapper that draws rooms from the game's `Room.Info` packets.
+Nothing else lives here: no game source, no tables, no rooms. The script's home is the private game repo
+(`lassiter-creek-world/clients/mudlet/`); this is the built copy. Current version: **9c165b60**.
+
+Connect: `mill.tail813f8a.ts.net` port `8443`, TLS on.
