 ## 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
@@ -9,11 +9,19 @@
 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.
+1. Clone sources with submodules: `git clone --recurse-submodules https://github.com/topjohnwu/Magisk.git`
+2. Building is supported on macOS, Linux, and Windows. Official releases are built and tested with [FrankeNDK](https://github.com/topjohnwu/FrankeNDK); point `ANDROID_NDK_HOME` to FrankeNDK if you want to use it for compiling.
+3. Set configurations in `config.prop`. A sample file `config.prop.sample` is provided as an example.
+4. 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`
+5. By default, `build.py` build binaries and Magisk Manager in debug mode. If you want to build Magisk Manager in release mode (via the `-r, --release` flag), you need a Java Keystore file `release-key.jks` (only `JKS` format is supported) to sign APKs and zips. For more information, check out [Google's Official Documentation](https://developer.android.com/studio/publish/app-signing.html#signing-manually).
