 How to write the SD card
 ========================
 
+The sdcard.img file is a complete bootable image ready to be written
+on the boot medium. To install it, simply copy the image to a uSD
+card:
 
-Prepare the SD card
--------------------
+    # dd if=output/images/sdcard.img of=/dev/sdX
 
-Erase existing stuff, and create an unique Linux partition with `fdisk`.

-    # fdisk /dev/sdX

-    Building a new DOS disklabel with disk identifier 0xf9e1616a.
-    Changes will remain in memory only, until you decide to write them.
-    After that, of course, the previous content won't be recoverable.
