+* Porting To A New Platform
+
+  The first thing you have to do when porting to a new platform, is look at
+include/SDL_platform.h and create an entry there for your operating system.
+The standard format is __PLATFORM__, where PLATFORM is the name of the OS.
+Ideally SDL_platform.h will be able to auto-detect the system it's building
+on based on C preprocessor symbols.
+
+There are two basic ways of building SDL at the moment:
+
+1. The "UNIX" way:  ./configure; make; make install
+
+   If you have a GNUish system, then you might try this.  Edit configure.in,
+   take a look at the large section labelled:
+	"Set up the configuration based on the target platform!"
+   Add a section for your platform, and then re-run autogen.sh and build!
+
+2. Using an IDE:
+
+   If you're using an IDE or other non-configure build system, you'll probably
+   want to create a custom SDL_config.h for your platform.  Edit SDL_config.h,
+   add a section for your platform, and create a custom SDL_config_{platform}.h,
+   based on SDL_config.h.minimal and SDL_config.h.in
+
+   Add the top level include directory to the header search path, and then add
+   the following sources to the project:
+	src/*.c
+	src/audio/*.c
+	src/cdrom/*.c
+	src/cpuinfo/*.c
+	src/events/*.c
+	src/file/*.c
+	src/joystick/*.c
+	src/stdlib/*.c
+	src/thread/*.c
+	src/timer/*.c
+	src/video/*.c
+	src/audio/disk/*.c
+	src/video/dummy/*.c
+	src/joystick/dummy/*.c
+	src/cdrom/dummy/*.c
+	src/thread/generic/*.c
+	src/timer/dummy/*.c
+	src/loadso/dummy/*.c
+
+
+Once you have a working library without any drivers, you can go back to each
+of the major subsystems and start implementing drivers for your platform.
+
+If you have any questions, don't hesitate to ask on the SDL mailing list:
+	http://www.libsdl.org/mailing-list.php
+
+Enjoy!
