            ## Flashing Guide

            ### 1. Merged firmware (easiest)

            Download `mimiclaw-full-${{ github.ref_name }}.bin` and flash with a single command:

            ```bash
            esptool.py --chip esp32s3 -b 460800 write_flash 0x0 mimiclaw-full-${{ github.ref_name }}.bin
            ```

            ### 2. Individual binaries (advanced)

            ```bash
            esptool.py --chip esp32s3 -b 460800 write_flash \
              0x0      bootloader-${{ github.ref_name }}.bin \
              0x8000   partition-table-${{ github.ref_name }}.bin \
              0xf000   ota_data_initial-${{ github.ref_name }}.bin \
              0x20000  mimiclaw-${{ github.ref_name }}.bin \
              0x420000 spiffs-${{ github.ref_name }}.bin
            ```

            ### 3. OTA update (for devices already running MimiClaw)

            Upload `mimiclaw-${{ github.ref_name }}.bin` via the OTA endpoint.

            ### 4. First-time setup

            After flashing, connect via serial (115200 baud) and configure:

            ```
            wifi <ssid> <password>
            tg_token <your-telegram-bot-token>
            api_key <your-anthropic-api-key>
            reboot
            ```
