             ##### `FBTURBOSRC_DIR`=""
             Path to a directory (`xf86-video-fbturbo`) of [hardware accelerated Xorg video driver sources](https://github.com/ssvb/xf86-video-fbturbo) that will be copied, configured, build and installed inside the chroot.
+            ##### `ENABLE_VIDEOCORE`=false
+            Install and enable the [Source code for ARM side libraries for interfacing to Raspberry Pi GPU](https://github.com/raspberrypi/userland) `vcgencmd`. Please note that this driver is currently limited to hardware accelerated window moving and scrolling.
+            ##### `VIDEOCORESRC_DIR`=""
+            Path to a directory (`userland`) of [Source code for ARM side libraries for interfacing to Raspberry Pi GPU](https://github.com/raspberrypi/userland) that will be copied, configured, build and installed inside the chroot.
             ##### `ENABLE_IPTABLES`=false
             Enable iptables IPv4/IPv6 firewall. Simplified ruleset: Allow all outgoing connections. Block all incoming connections except to OpenSSH service.
