+## Activating the venv
+
+Two venvs exist — one for Windows, one for WSL:
+
+```bash
+# WSL / Linux
+source venv-wsl/bin/activate
+
+# Windows (PowerShell)
+.\venv\Scripts\Activate.ps1
+
+# Windows (cmd)
+.\venv\Scripts\activate.bat
+```
+
+Deactivate either with `deactivate`.

+## Developer TUI
+
+`kao_tui.py` is a terminal UI for firing test events, faces, and sounds at a running Kao instance — no `curl` needed.
+
+```bash
+python kao_tui.py                        # connect to http://localhost:5100
+python kao_tui.py http://192.168.1.x:5100  # custom URL
+```
+
+Four tabs:
+- **Sounds** — fire any of the 17 sounds via `/notify`
+- **Faces** — send any preset emote/animation combo via `/notify`
+- **Events** — post Critical/Warning/Notify events (10s TTL) or clear all
+- **Controls** — Sleep, Wake, Clear all
+
+Navigate with `↑↓` or `Tab`, press `Enter` to fire, `Q` to quit. A toast confirms each action.
