 ## What you get
 - **Firmware** (`switch-pico.cpp` + `switch_pro_driver.*`): acts as a wired Switch Pro. Takes controller reports over UART1 and passes rumble from the Switch back over UART.
-- **Python bridge** (`controller_uart_bridge.py`): reads SDL2 controllers on the host, sends reports over UART, and applies rumble locally. Hot‑plug friendly and cross‑platform (macOS/Windows/Linux).
+- **Python bridge** (`switch_pico_bridge.controller_uart_bridge` / CLI `controller-uart-bridge`): reads SDL2 controllers on the host, sends reports over UART, and applies rumble locally. Hot‑plug friendly and cross‑platform (macOS/Windows/Linux).

    - Leave VBUS/VCC unconnected unless your adapter explicitly supports 3.3 V power output and you intend to power the Pico from it (the bridge expects the Pico to be powered from USB instead).
 
 3. **Connect everything to the host and Switch**
-   - Plug the USB-to-UART adapter into the computer that will run `controller_uart_bridge.py`. Note the COM port (`Device Manager > Ports`) on Windows or `/dev/cu.*`/`/dev/ttyUSB*` path on macOS/Linux; pass it via `--map`/`--ports`.

    - Connect the Pico's micro USB port to the Nintendo Switch (via the dock's USB-A port, a USB-C OTG adapter, or a PC if you are only testing). The Pico enumerates as a Switch Pro Controller over USB.
    - Any SDL-compatible gamepads you want to use should also be plugged into (or paired with) the same host computer that runs the Python bridge; the bridge is the one reading them.
 
 4. **Power-on order and sanity checks**
    - Power the Switch/dock so the Pico gets 5 V over USB; its USB stack must stay alive while the bridge streams data.
-   - On the host computer, run `python controller_uart_bridge.py --list-controllers` to make sure SDL sees your pads, then start the bridge with `--map`/`--ports` (or `--interactive`) referencing the adapter path you found earlier.

    - Watch the Rich console output: you should see each controller paired with a UART port and the rumble loop logging reconnects if cables are unplugged.
 
 5. **Common pitfalls**
    - A flipped TX/RX pair results in silence (no button presses); swap them if the Pico never shows input.
    - Some adapters default to 5 V logic—move the jumper to 3.3 V before touching the Pico.
    - If you use multiple adapters, label each cable; COM port numbers can change between boots.
