+The board needs to be put into bootloader mode before upgrading.
+
+To do it: Hold down **BOOT** and then press **RST** once, finally release **BOOT**.
+
+Program your board using the esptool.py program, found [here](https://github.com/espressif/esptool).
+
+If you are putting MicroPython on your board for the first time then you should
+first erase the entire flash using:
+
+```bash
+python -m esptool --chip esp32s2 --port /dev/ttyACM0 erase_flash
+```
+
+From then on program the firmware starting at address `0x1000`:
+
+```bash
+python -m esptool --chip esp32s2 --port /dev/ttyACM0 write_flash -z 0x1000 firmware.bin
+```
+
+`/dev/ttyACM0` is the port format of Linux, in MacOS it might be `/dev/cu.usbmodem01`, in Windows it might be `COM1`, need to confirm the port number of the board.
+
+`firmware.bin` should be the filename of the firmware you want to use.
+
+When the program is finished, press RST.
