 There are two ways to use PrawnOS. 
 
-The first option is to boot from the external USB or SD device you wrote the image to, and expand the image to take up the entire boot device.

-* Expanding the PrawnOS image allows you to boot PrawnOS from the same USB or SD device that you wrote the image to
-* Expansion does _NOT_ support root encryption. For root encryption the filesystem must be written after the encrypted root is created.

 * This lets you install PrawnOS to the internal emmc, an SD card or a USB device
 * This allows you to setup root encryption
 * Installing to an external device allows you to try PrawnOS without removing Chrome OS or whatever Linux you are running on your internal storage (emmc), but USB drives especially are a much slower experience as the c201 only has USB 2.0.
+* The internal emmc is much faster than a usb device or sd card for both reads and writes, data from some tests is available in #133
 * If you want to boot from external media, I would suggest using an SD card.

 ### Install to internal drive (emmc) or to SD card or USB drive
 Now on the C201, insert the drive you wrote the PrawnOS image to. Press `control+u` at boot to boot from the external drive.
