 # Magisk
 
-## How to build 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)
 
-#### Building has been tested on 3 major platforms:
+## Introduction
 
-***macOS 10.12.5***  
-***Ubuntu 17.04 x64***  
-***Windows 10 Creators Update x64***  
+Magisk is a suite of open source tools for customizing Android, supporting devices higher than Android 4.2 (API 17). It covers the fundamental parts for Android customization: root, boot scripts, SELinux patches, AVB2.0 / dm-verity / forceencrypt removals etc.
 
-#### Environment Requirements
+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).
 
-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  
+## Bug Reports
 
-#### Instructions and Notes
+**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.
 
-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](https://developer.android.com/studio/publish/app-signing.html#signing-manually)
-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.  
+## Building Environment Requirements
+
+-  Python 3: run `build.py` script
+-  Java Development Kit (JDK) 8: Compile Magisk Manager and sign zips
+-  Latest Android SDK: set `ANDROID_HOME` environment variable to the path to Android SDK
+-  Android NDK: Install NDK along with SDK (`$ANDROID_HOME/ndk-bundle`), or optionally specify a custom path `ANDROID_NDK_HOME`
+-  (Windows Only) Python package Colorama: Install with `pip install colorama`, used for ANSI color codes
+
+## Building Notes and Instructions
+
+-  Clone sources with submodules: `git clone --recurse-submodules https://github.com/topjohnwu/Magisk.git`
+-  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.
+-  Set configurations in `config.prop`. A sample file `config.prop.sample` is provided as an example.
+-  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`
+-  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).
+
+## Translations
+
+Default string resources for Magisk Manager are scattered throughout
+
+- `app/src/main/res/values/strings.xml`
+- `stub/src/main/res/values/strings.xml`
+- `shared/src/main/res/values/strings.xml`
+
+Translate each and place them in the respective locations (`<module>/src/main/res/values-<lang>/strings.xml`).
+
+## Signature Verification
+
+Official release zips and APKs are signed with my personal private key. You can verify the key certificate to make sure the binaries you downloaded are not manipulated in anyway.
+
+``` bash
+# Use the keytool command from JDK to print certificates
+keytool -printcert -jarfile <APK or Magisk zip>
+
+# The output should contain the following signature
+Owner: CN=John Wu, L=Taipei, C=TW
+Issuer: CN=John Wu, L=Taipei, C=TW
+Serial number: 50514879
+Valid from: Sun Aug 14 13:23:44 EDT 2016 until: Tue Jul 21 13:23:44 EDT 2116
+Certificate fingerprints:
+	 MD5:  CE:DA:68:C1:E1:74:71:0A:EF:58:89:7D:AE:6E:AB:4F
