+This directory contains the interface for the Raspberry Pi framebuffer.
+This talks directly to the raspberry pi hardware (not via a linux framebuffer driver).
+
+This graphics interface is software driven - it is not an accelerated interface.
+
+This board definition should work on any operating system that will work on the Raspberry Pi
+	eg. Linux, FreeRTOS.
+
+On this board uGFX currently supports:
+	- GDISP via the framebuffer driver 
+
+THe following variables may optionally be defined in your gfxconf.h or your makefile...
+	- GDISP_LLD_PIXELFORMAT			default = GDISP_PIXELFORMAT_RGB565
+	- GDISP_SCREEN_WIDTH			default = 800
+	- GDISP_SCREEN_HEIGHT			default = 600
+
+Note that this also provides a Raspberry Pi specific api defined in rpi_mailbox.h to talk
+directly to the graphics co-processor from the ARM processor.
