+================================================================================
+SDL2 for Raspberry Pi
+================================================================================
+
+Requirements:
+
+Raspbian (other Linux distros may work as well).
+
+================================================================================
+ Features
+================================================================================
+
+* Works without X11
+* Hardware accelerated OpenGL ES 2.x
+* Sound via ALSA
+* Input (mouse/keyboard/joystick) via EVDEV
+* Hotplugging of input devices via UDEV
+
+================================================================================
+ Raspbian Build Dependencies
+================================================================================
+
+sudo apt-get install libudev-dev libasound2-dev
+
+You also need the VideoCore binary stuff that ships in /opt/vc for EGL and
+OpenGL ES 2.x, it usually comes pre installed, but in any case:
+
+sudo apt-get install libraspberrypi0 libraspberrypi-bin libraspberrypi-dev
+
+================================================================================
+ No HDMI Audio
+================================================================================
+
+If you notice that ALSA works but there's no audio over HDMI, try adding:
+
+ hdmi_drive=2
+
+to your config.txt file and reboot.
+
+Reference: http://www.raspberrypi.org/phpBB3/viewtopic.php?t=5062
+
+================================================================================
+ Notes
+================================================================================
+
+* Building has only been tested natively (i.e. not cross compiled). Cross
+ compilation might work though, feedback is welcome!
+* No Text Input yet.
