 ## Flashing Image to SD Card
 
-To flash the image to the SD card, use the `create-sdcard.sh` script.
+If you just want to flash the built image to the SD card, use the
+`create-sdcard.sh` script.
 Syntax:
 
 ```bash
 sudo ./create-sdcard.sh <build>

+## Creating SD Card Image
+
+To create a shareable SD card Image to flash with tools like balena-etcher, use

+
+```bash
