 # Magisk
+[Downloads](https://github.com/topjohnwu/Magisk/releases) | [Documentation](https://topjohnwu.github.io/Magisk/) | [XDA Thread](https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445)
+
+## Introduction
+Magisk is a suite of open source tools for customizing Android, supporting devices higher than Android 5.0 (API 21). It covers the fundamental parts for Android customization: root, boot scripts, SELinux patches, AVB2.0 / dm-verity / forceencrypt removals etc.
+
+Furthermore, Magisk provides a **Systemless Interface** to alter the system (or vendor) arbitrarily while the actual partitions stay completely intact. With its systemless nature along with several other hacks, Magisk can hide modifications from nearly any system integrity verifications used in banking apps, corporation monitoring apps, game cheat detections, and most importantly [Google's SafetyNet API](https://developer.android.com/training/safetynet/index.html).
+
+## Bug Reports
+**Make sure to install the latest [Canary Build](https://forum.xda-developers.com/apps/magisk/dev-magisk-canary-channel-bleeding-edge-t3839337) before reporting any bugs!** **DO NOT** report bugs that is already fixed upstream. Follow the instructions in the [Canary Channel XDA Thread](https://forum.xda-developers.com/apps/magisk/dev-magisk-canary-channel-bleeding-edge-t3839337), and report a bug either by opening an issue on GitHub or directly in the thread.
 
 ## 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

 5. (Windows Only) Python package Colorama: Install with `pip install colorama`, used for ANSI color codes
 
 ## Building Notes and Instructions
-1. Building is supported on macOS, Linux, and Windows using the custom NDK: [FrankeNDK](https://github.com/topjohnwu/FrankeNDK).
+1. Clone sources with submodules: `git clone --recurse-submodules https://github.com/topjohnwu/Magisk.git`
-2. Set configurations in `config.prop`. A sample file `config.prop.sample` is provided as an example.
+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. 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`
+3. Set configurations in `config.prop`. A sample file `config.prop.sample` is provided as an example.
-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 `-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).
