             ##### `ENABLE_UBOOT`=false
             Replace default RPi2 second stage bootloader (bootcode.bin) with U-Boot bootloader. U-Boot can boot images via the network using the BOOTP/TFTP protocol.
+            ##### `ENABLE_FBTURBO`=false
+            Install and enable the hardware accelerated Xorg video driver `fbturbo`. Please note that this driver is currently limited to hardware accelerated window moving and scrolling.
             ##### `ENABLE_IPTABLES`=false
             Enable iptables IPv4/IPv6 firewall. Simplified ruleset: Allow all outgoing connections. Block all incoming connections except to OpenSSH service.
