 ## How to build Magisk
 
-#### Building has been tested on 3 major platforms:
+#### Building has been tested on 3 major platforms: macOS, Ubuntu, Windows 10
 
-**macOS 10.12**  
-**Ubuntu 17.04 x64**  
-**Windows 10 x64**
-
-#### Environment Requirements
+### Environment Requirements
 
 1. A 64-bit machine: `cmake` for Android is only available in 64-bit
-2. Python 3.5+: to run the build script
-3. Java Development Kit (JDK) 8: To compile Magisk Manager and sign zips
-4. C compiler (Unix only): To build `zipadjust`. Windows users can use the pre-built `zipadjust.exe`
-5. Android SDK: `ANDROID_HOME` environment variable should point to the Android SDK folder
-6. Android NDK: Install NDK via `sdkmanager`, or via Android SDK Manager in Android Studio
+2. Python 3.5+: run `build.py` script
+3. Java Development Kit (JDK) 8: Compile Magisk Manager and sign zips
+4. Latest Android SDK: `ANDROID_HOME` environment variable should point to the Android SDK folder
+5. Android NDK: Install NDK along with SDK (`$ANDROID_HOME/ndk-bundle`), or specify custom path `ANDROID_NDK`
+6. (Windows Only) Python package Colorama: Install with `pip install colorama`, used for ANSI color codes
+7. (Unix only) C compiler: Build `zipadjust`. Windows users can use the pre-built `zipadjust.exe`
 
-#### Instructions and Notes
-
-1. The easiest way to setup a working environment is to open Magisk Manager with Android Studio. The IDE will download required components and construct the environment for you. Don't forget to set `ANDROID_HOME` environment variable to the SDK path.
-2. Windows users: while installing Python 3 on Windows, allow the installer to add Python to `PATH`, or you'll have to add it manually afterwards. By default, the Python executable is setup as `python`, not `python3` like most Unix environment. If you have both Python 2 and Python 3 installed, you'll have to deal with the executable name and `PATH` yourself. To double check the Python version, call `python --version`.
-3. To run the script, on Windows call `python build.py [args...]`; on Unix call `python3 build.py [args...]`, or simply `./build.py [args...]`. To see the built-in help message, call the script with `-h` as an argument. The `-h` option also works for each supported actions to see the help message for the specific action.
-4. By default, the script will build binaries and Magisk Manager in debug mode, which will enable verbose debugging messages. If you want to build Magisk Manager in release mode (through the flag `--release`), you will need to place your Java Keystore file in `release_signature.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 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 use an older Windows version, a quick Google search should provide many workarounds.
+### Instructions and Notes
+1. Magisk can be built with the latest NDK (r16 as of writing), however binaries released officially will be built with NDK r10e due to ELF incompatibilities with the binaries built from the newer NDKs.
+2. The easiest way to setup the environment is by importing this folder as an Android Studio project. The IDE will download required components and construct the environment for you. You still have to set the `ANDROID_HOME` environment variable to point to the SDK path.
+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. Build everything with `build.py`, don't directly call `gradlew` or `ndk-build`, since most requires special setup / dependencies.
+5. By default, `build.py` will build binaries and Magisk Manager in debug mode. If you want to build Magisk Manager in release mode (through the flag `--release`), you will need to place a Java Keystore file at `release_signature.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).
