+## Compiling ##
 
-## Building ##
+### Windows ###
 1) Open the solution in VS2015  
 2) Compile as Release/x64  
 3) Run  
 
+### Linux ###
+You will need clang/gcc, Mono/XBuild and SDL2 to compile and run Mesen under Linux.
+A makefile is included - running "make" and then "make run" should start the emulator.
 
-### LICENSE ###
+A few limitations remain in the Linux version at the moment, which is why there is no official Linux build yet.
+Most importantly, gamepads/controllers are not supported.
