 ## What’s inside
 - ESP‑IDF firmware (C/C++) with modules for Camera, Wi‑Fi, UVC, REST/Serial commands, and more
-- Python tools to make setup easy over USB serial:
+- Python tools for setup over USB serial:
-  - `tools/switchBoardType.py` — choose a board profile (loads the right sdkconfig)
+  - `tools/switchBoardType.py` — choose a board profile (builds the right sdkconfig)
   - `tools/openiris_setup.py` — interactive CLI for Wi‑Fi, MDNS/Name, Mode, LED PWM, Logs, and a Settings Summary
-  - `tools/wifi_scanner.py` — optional Wi‑Fi scanner

-## Prerequisites
-- ESP‑IDF installed and available in your terminal (`idf.py` works)
-- Python 3.10+ with `pip` (on Windows this is installed automatically when you set up the ESP‑IDF VS Code extension; see “First-time setup on Windows” below)
-- USB cable to your board
-- Optional: install Python dependencies for the tools

-Windows (cmd):
-```cmd
-python -m pip install -r tools\requirements.txt
-```
-macOS/Linux (bash):
-```bash
-python3 -m pip install -r tools/requirements.txt
-```
-Note for Windows: If emojis don’t render nicely, it’s only cosmetic — everything still works.

-6) Default board profile and switching
-- The project ships with multiple board profiles; one default may target internal “Project Babble” boards.
-- If you have a Seeed XIAO ESP32S3 (or another board), switch the profile with the helper script:

-- You can re‑run this anytime to switch boards; `--diff` shows the changes.

 After this, you’re ready for the Quick start below.

 ## Troubleshooting
-- No device/port found?
-  - Pass `--port` explicitly (e.g., `--port COM15`).
-  - Right after reset, the device emits heartbeats for a short time; the CLI finds it fastest during that window.
 - UVC doesn’t appear on the host?
-  - Switch mode to UVC and replug USB. On Windows the first driver init can take a moment.
+  - Switch mode to UVC via CLI tool, replug USB and wait 20s.
-- Wi‑Fi won’t connect?
-  - Check password/channel. Use the automatic setup in the CLI and then inspect the status.
-- ESP‑IDF not detected?
-  - Ensure the ESP‑IDF environment is active in the terminal (IDF Command Prompt or the extension’s ESP‑IDF Terminal; alternatively source `export.ps1`/`export.sh`).
-- Missing Python modules?
-  - Run `pip install -r tools/requirements.txt`.
