+
+This is the FOG USB image. It is designed to register machines,  as well as deploy and capture images from a FOG server on machines that have trouble with PXE.
+
+To use this image, you will need to create a bootable USB stick. You can use the following command to write this image to a USB stick:
+
+dd if=fos-usb.img of=/dev/sdX bs=1M
+
+Where /dev/sdX is the device name of your USB stick. Be very careful with this command, as it can destroy data on your hard drive if you specify the wrong device.
+
+Once you have written the image to the USB stick, you can boot the target system from the USB stick. The system will boot into a FOG menu that will allow you to capture an image, deploy an image, register a host, or run a memory test.
