 ###How to build Magisk
-1. Only support MacOS and Linux
-2. Download and install NDK
-3. Add the NDK directory into PATH.  
-To check if success, please try calling `which ndk-build` and see if it returns the NDK directory
-4. Execute `./build.sh`, it will give you further information
+1. Download and install NDK
+2. Add the NDK directory into PATH  
+To check if the PATH is set correctly, try calling `which ndk-build` (`where ndk-build` on Windows) and see if it shows the NDK directory
+3. Unix-like users (e.g. Linux & MacOS) please execute `build.sh` through shell  
+Windows users please execute `build.cmd` through cmd
+4. The scripts will show you further details
