 ### Installing SDL2 & SDL2_image
 
-This will install the SDL2 development headers and libraries into `/usr/local/cross-tools/x86_64-w64-mingw32/`.
+This will install the SDL2 64bit mingw development headers and libraries into `/opt/local/x86_64-w64-mingw32/`.
 
-If you use a different directory then you will have to supply the SDL2 dir to the `cmake` command below using `-DSDL2_DIR`. For example: `cmake .. -DCMAKE_TOOLCHAIN_FILE=../mingw.toolchain -DSDL2_DIR=/usr/local/cross-tools/x86_64-w64-mingw32/lib/cmake/SDL2`
+Note: the `lib/cmake/SDL2/sdl2-config.cmake` shipped with these libraries expects them to be in `/opt/local`, if you change the install path you will have to modify this file.
 
-First, make sure the `cross-tools` directory (or your chosen alternative) exists:
