Windows 10 Creators Update x64

1. Python 3 (>= 3.5): python3 (or in some cases python) should be accessible
2. Java runtime: java should be accessible
3. (Unix only) C compiler: gcc should be accessible
4. Android SDK: ANDROID_HOME environment variable should point to the Android SDK folder
5. NDK: Install NDK using sdkmanager, or through Android SDK Manager
6. Android build-tools: Should have build-tools version matching MagiskManager/app/build.gradle installed

1. The python build script uses ANSI color codes to change the color of the terminal output. For Windows, this only works on Windows 10, as previous Windows console do not support them. If you insist to use an older Windows version, a quick Google search should provide many workarounds
2. After installing the latest Python 3 on Windows (allow the installer to add Python to PATH, or you'll have to manually set the environment), instead of calling python3 like most Unix environment, you should call python in shell (cmd or Powershell both OK). You can double check the version by python --version
3. The build script will do several checks, it will refuse to run if the environment doesn't meet the requirements
4. For further instructions, please check the built in help message by python3 build.py -h
   (Unix users can simply ./build.py -h, Windows users, as mentioned, call python instead)
5. Each action has its own help message, access them by commands like python3 build.py all -h
6. To build Magisk for release (enabled through the --release flag, the script builds in debug mode by default), you will need to provide a Java keystore file, and place it in release_signature.jks to sign Magisk Manager APK for release builds. For more information, check out Google's Official Documentation
7. To properly setup the Android SDK environment, the easiest way is to use Android Studio and open Magisk Manager. If gradle sync passed, your build-tools etc. should be set properly. You can also access SDK Manager GUI within Android Studio to download NDK. Don't forget to add Android Studio's SDK path into environment variable ANDROID_HOME.
