+# Magisk
+
+## Building Environment Requirements
+
+1. Python 3.5+: run `build.py` script
+2. Java Development Kit (JDK) 8: Compile Magisk Manager and sign zips
+3. Latest Android SDK: set `ANDROID_HOME` environment variable to the path to Android SDK
+4. Android NDK: Install NDK along with SDK (`$ANDROID_HOME/ndk-bundle`), or optionally specify a custom path `ANDROID_NDK_HOME`
+5. (Windows Only) Python package Colorama: Install with `pip install colorama`, used for ANSI color codes
+
+## Building Notes and Instructions
+1. Building is tested on macOS, Ubuntu, and Windows 10 using the latest stable NDK and NDK r10e. Officially released binaries were built with NDK r10e.
+2. Set configurations in `config.prop`. A sample file `config.prop.sample` is provided as an example.
+3. Run `build.py` with argument `-h` to see the built-in help message. The `-h` option also works for each supported actions, e.g. `./build.py binary -h`
+4. By default, `build.py` build binaries and Magisk Manager in debug mode. If you want to build Magisk Manager in release mode (via the `--release` flag), you need a Java Keystore file `release-key.jks` to sign Magisk Manager's APK. For more information, check out [Google's Official Documentation](https://developer.android.com/studio/publish/app-signing.html#signing-manually).
+5. The SafetyNet extension pack requires the full Magisk Manager as a `compileOnly` dependency. Build the **release** APK, convert it back to Java `.class` files (I use [dex2jar](https://github.com/pxb1988/dex2jar)), and place the converted JAR under `snet/libs` before compiling.

-# Magisk Manager
-The project should be built with Android Studio version 2.2.0+  
-I use Java 8 features, which requires Jack compiler and it's only available in 2.2.0+  
-Also, you need to install CMake and NDK to build the zipadjust library for zip preprocessing
