+Windows Setup
+----------------------
+
+Compiling on Windows does work, just it's a bunch more work.
+
+First make sure Cygwin is installed - http://www.cygwin.com/ - 32bit or 64bit is fine. Make sure the following are installed:
+- make
+- git (needed for some compilation info)
+
+And make sure CMake is *NOT* installed through Cygwin. This is extremely important.
+If this is not possible, you'll have to play with your paths in Cygwin to prioritize the Windows version of CMake.
+
+Install the latest version of CMake - http://cmake.org/cmake/resources/software.html
+Make sure to have CMake add itself to at least your PATH in the installer.
+(If this errors out, you'll have to add CMake to your .bashrc path).
+
+Next, install the compiler(s) you want.
+
+ ---------
+| AVR GCC |
+ ---------
+
+You just need the Atmel AVR 8-bit Toolchain. The latest should be fine, as of writing it was 3.4.3.
+
+http://www.atmel.com/tools/atmelavrtoolchainforwindows.aspx
+
+Extract the files to a directory, say C:\avr8-gnu-toolchain. Then copy all the folders in that directory to the Cygwin directory.
+Mine is C:\cygwin64.
+(You can also just setup the paths, but this is faster/simpler. Might screw up your Cygwin though).
+
+
+ ----------
+| ARM EABI |
+ ----------
+
+Download the latest version of Mentor Graphics Sourcery CodeBench ARM EABI.
+
+http://www.mentor.com/embedded-software/sourcery-tools/sourcery-codebench/editions/lite-edition/
+
+Use the installer and make sure you add the binaries to your path within the installer.
