+![A real Moyu play session captured from a text-only terminal](./docs/media/moyu-real-play.gif)
+
+The clip above is a real play session in the text fallback tier, recorded without a coding CLI. High-resolution terminals can render finer graphics; `moyu doctor --caps` shows which tier your terminal selects.
+
+- **Actual play:** run `moyu demo` after installation. This uses your terminal's available graphics tier and starts at normal progression.
+- **Sword-art showcase:** from a source checkout, run `npm run showcase:en` for a 26-second sequence of all seven arts. It starts with unlocked moves and full qi for recording, so it is a staged showcase rather than a normal run. See the [recording guide](./docs/showcase.md).
+- **Beside an agent:** run `moyu -- codex` or `moyu -- claude`, then press `Ctrl+]` while the agent is working. Press it again to return to the same coding session.
+
+Moyu needs Node 20+ and an interactive terminal. Graphics quality depends on your terminal; use `moyu doctor --caps` to see the selected tier. [Open a terminal report](https://github.com/PrometheusTT/moyu/issues/new) if the game does not render correctly, including your OS, terminal, and `doctor --caps` output.

 ## Controls
 
 When Moyu wraps a coding CLI, keys belong to that CLI until you enter the game.
