 At this point, if you optionally want to compile the provided examples for the web, there is another Makefile to configure. Make sure all paths to emscripten installation (`EMSDK_PATH`) and emscripten required tools (Clang, Python, Node) are correctly configured on `raylib/examples/Makefile`, you must verify [these lines](https://github.com/raysan5/raylib/blob/master/examples/Makefile#L134).
 
 #### For Windows users :
 
-Start up Notepad++ for raylib, open the `raylib/examples/Makefile` file, press F6, choose `raylib_makefile`, verify that in the script the web platform is set (`SET PLATFORM=PLATFORM_WEB`) and click OK to run the script. It will compile all the examples for the web.
