+These files are required to flash the Mendel Linux OS to an attached device
+using fastboot:
+
+1. On your host computer, install the `fastboot` tool.
+2. Using either the serial console or the `fastboot` tool, put the device into
+   fastboot mode (`sudo reboot-bootloader`).
+3. Connect to the device using a USB cable, attached to the device's USB data
+   "OTG" port.
+4. Run the `flash.sh` script in this directory.
+
+For detailed instructions, visit coral.ai/docs/setup.
+
+If your board fails to boot, `enable_lk_fastboot.sh` can be used to get your
+device into fastboot mode. Please see https://coral.ai/docs/dev-board-mini/reflash/
+for more details.
