+Program your board using the esptool.py program, found
+[here](https://github.com/espressif/esptool).
+
+To put the TinyC6 into 'download mode', hold the _BOOT_ button while connecting
+the USB cable. It can be released after the connection is made.
+
+If you are putting MicroPython on your board for the first time then you should
+first erase the entire flash using:
+
+```bash
+esptool.py --chip esp32c6 --port /dev/ttyUSB0 erase_flash
+```
+
+From then on program the firmware starting at address 0x0:
+
+```bash
+esptool.py --chip esp32c6 --port /dev/ttyUSB0 --baud 460800 write_flash -z 0x0 esp32c6-20220117-v1.18.bin
