+Program your board using the latest version of the esptool.py program, found [here](https://github.com/espressif/esptool).
+
+To flash or erase your TinyWATCH S3, you have to first put it into download mode.
+To do this, follow these steps:
+
+- Press and hold the [BOOT] button
+- Press and release the [RESET] button
+- Release the [BOOT] button
+
+Now the board is in download mode and the native USB will have enumerated as a serial device.
+
+If you are putting MicroPython on your board for the first time then you should
+first erase the entire flash using:
+
+### Linux
+```bash
+esptool.py --chip esp32s3 --port /dev/ttyACM0 erase_flash
+```
+
+### Mac
+Please do a `ls /dev/cu.usbm*` to determine the port your board has enumerated as.
+```bash
+esptool.py --chip esp32s3 --port /dev/cu.usbmodem01 erase_flash
+```
+
+### Windows
+Change (X) to whatever COM port is being used by the board
+```bash
+esptool --chip esp32s3 --port COM(X) erase_flash
+```
+
+Now download the version of the firmware you would like to install from the options below,
+then use the following command to program the firmware starting at address 0x0,
+remembering to replace `tinywatchs3-micropython-firmware-version.bin` with the name of
+the firmware you just downloaded:
+
+### Linux
+```bash
+esptool.py --chip esp32s3 --port /dev/ttyACM0 write_flash -z 0x0 tinywatchs3-micropython-firmware-version.bin
+```
+
+### Mac
+Please do a `ls /dev/cu.usbm*` to determine the port your board has enumerated as.
+```bash
+esptool.py --chip esp32s3 --port /dev/cu.usbmodem01 write_flash -z 0x0 tinywatchs3-micropython-firmware-version.bin
+```
+
+### Windows
+Change (X) to whatever COM port is being used by the board
+```bash
+esptool --chip esp32s3 --port COM(X) write_flash -z 0x0 tinywatchs3-micropython-firmware-version.bin
