+### Factory Images Method
+
+Factory Images are one of the easier way to install a image onto a device, and is reccomended for new users. It is similar to the fastboot method, but all the binary objects and a flashall.sh script are provided in a single zip file, so one doesn't need to make sure they have the right versions of various binary images, nor remember which order might be required to flash images.
+
+This method requires the following hardware:
+
+- HiKey with power supply
+- Host machine (Linux, Possibly MacOS?)
+- USB to microUSB cable
+- HDMI Monitor with full size HDMI cable (not required to perform flash)
+
+Go to the [Downloads page](../Downloads/README.md) to get your Factory Image zip file.
