 # Twungeon
 
-Twungeon as a Twitch-controlled cooperative dungeon game.
+Twungeon is a Twitch-controlled cooperative dungeon game in which viewers watch
+a shared world on stream, join through Twitch chat, and control individual
+characters with a Twitch Extension.
+
+## Project status
+
+Twungeon is in pre-implementation planning. The MVP product requirements and
+technical specification are approved, and the acceptance-test/build checklist
+is ready to guide implementation. No runtime MVP behavior or live Twitch
+integration is claimed complete yet.
+
+## Planning documents
+
+- [MVP Product Requirements Document](Twungeon_MVP_PRD_Current.md) — defines the
+  product boundary and 33 success criteria.
+- [MVP Technical Specification](Twungeon_MVP_Technical_Specification.md) —
+  defines the approved architecture, authoritative state, rules, contracts, and
+  failure behavior.
+- [MVP Acceptance-Test and Build Checklist](Twungeon_MVP_Acceptance_Test_and_Build_Checklist.md)
+  — sequences implementation and defines the evidence required for each success
+  criterion.
+
+The PRD is authoritative for product scope. The specification and checklist
+must be updated alongside any approved requirement change.
+
+## Initial technical direction
+
+The MVP is planned around TypeScript, RPGJS, Twurple, and a Twitch Extension,
+with Twungeon's game rules isolated from framework and service adapters where
+practical.
+
+Public project and development-log records are maintained under `.labyricorn/`.
