+            ## 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
+            ```
+
+            ### 3. OTA update (for devices already running MimiClaw)
+
+            Upload `mimiclaw-${{ github.ref_name }}.bin` via the OTA endpoint.
+
+            ### 4. First-time setup
+
+            After flashing, connect via serial (115200 baud) and configure:
+
+            ```
+            wifi <ssid> <password>
+            tg_token <your-telegram-bot-token>
+            api_key <your-anthropic-api-key>
+            reboot
+            ```
+          files: |
+            mimiclaw-full-${{ github.ref_name }}.bin
+            mimiclaw-${{ github.ref_name }}.bin
+            bootloader-${{ github.ref_name }}.bin
+            partition-table-${{ github.ref_name }}.bin
