+## TUI
+
+| Property | Value |
+|----------|-------|
+| PyPI | [`birdcage-tui`](https://pypi.org/project/birdcage-tui/) |
+| Source | `tui/src/birdcage_tui/` |
+| Entry point | `birdcage_tui.app:main` |
+| Framework | [Textual](https://textual.textualize.io/) |
+| Screens | Dashboard (F1), Control (F2), Signal (F3), System (F4), Console (F5), Camera (F6) |
+
+### Running
+
+```bash
+# Published package (from PyPI) — no clone needed
+uvx birdcage-tui --demo                          # demo mode, base install
+uvx birdcage-tui                                  # hardware mode (needs serial port)
+
+# With camera capture support (Pillow + astropy)
+uvx --with 'birdcage-tui[camera]' birdcage-tui --demo
+
+# Local development
+uv run --directory tui birdcage-tui --demo
+```
+
+### Extras
+
+| Extra | Install | Packages | Purpose |
+|-------|---------|----------|---------|
+| *(base)* | `uvx birdcage-tui` | `winegard-birdcage`, `textual` | Full TUI, all screens, demo mode |
+| `camera` | `uvx --with 'birdcage-tui[camera]' birdcage-tui` | `Pillow>=10.0`, `astropy>=6.0` | F6 camera overlay: JPEG capture frames with annotated demo images (Pillow), FITS export for radio astronomy pipelines (astropy) |
+
+**Graceful degradation:** The camera screen (F6) works without the `camera` extra — it
+falls back to writing minimal JPEG headers directly. Pillow adds annotated demo frames
+and proper image processing; astropy adds FITS file export for integration with DS9,
+CASA, and other radio astronomy tools.
