-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
+## Introduction
-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.
+Magisk is a suite of open source tools for customizing Android, supporting devices higher than Android 4.2. It covers fundamental parts of Android customization: root, boot scripts, SELinux patches, AVB2.0 / dm-verity / forceencrypt removals etc.
-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`
+Here are some feature highlights:
-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).
+
+- **MagiskSU**: Provide root access to your device
+- **Magisk Modules**: Modify read-only partitions by installing modules
+- **MagiskHide**: Hide Magisk from root detections / system integrity checks

 ## 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!** Please **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.
+Canary Channels are cutting edge builds for those adventurous. To access canary builds, install the Canary Magisk Manager, switch to the Canary Channel in settings and upgrade.
 
-## Documentation
+**Only bug reports from Canary builds will be accepted.**
-[Link to Documentation](docs/README.MD)
+
+For installation issues, upload both boot image and install logs.<br>
+For Magisk issues, upload boot logcat or dmesg.<br>
+For Magisk Manager crashes, record and upload the logcat when the crash occurs.
+
+## Building and Development
+
+- Magisk builds on any OS Android Studio supports. Install Android Studio and do the initial setups.
+- Clone sources: `git clone --recurse-submodules https://github.com/topjohnwu/Magisk.git`
+- Install Python 3.6+ \
+(Windows only: select **'Add Python to PATH'** in installer, and run `pip install colorama` after install)
+- Configure to use the JDK bundled in Android Studio:
+	- macOS: `export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home"`
+	- Linux: `export PATH="/path/to/androidstudio/jre/bin:$PATH"`
+	- Windows: Add `C:\Path\To\Android Studio\jre\bin` to environment variable `PATH`
+- Set environment variable `ANDROID_SDK_ROOT` to the Android SDK folder (can be found in Android Studio settings)
+- Run `./build.py ndk` to let the script download and install NDK for you
+- Set configurations in `config.prop`. A sample `config.prop.sample` is provided.
+- To start building, run `build.py` to see your options. \
+For each action, use `-h` to access help (e.g. `./build.py all -h`)
+- To start development, open the project in Android Studio. Both app (Kotlin/Java) and native (C++/C) source code can be properly developed using the IDE, but *always* use `build.py` for building.
+- `build.py` builds in debug mode by default. If you want release builds (with `-r, --release`), you need a Java Keystore to sign APKs and zips. For more information, check [Google's Documentation](https://developer.android.com/studio/publish/app-signing.html#generate-key).
+
+## Translation Contributions
+
+Default string resources for Magisk Manager and its stub APK are located here:
+
+- `app/src/main/res/values/strings.xml`
+- `stub/src/main/res/values/strings.xml`
+
+Translate each and place them in the respective locations (`[module]/src/main/res/values-[lang]/strings.xml`).

+     * 2. Enable much faster signature and integrity verification. This is achieved by requiring
+     *    only a minimal amount of APK parsing before the signature is verified, thus completely
+     *    bypassing ZIP entry decompression and by making integrity verification parallelizable by
+     *    employing a hash tree.

+     * JAR and ZIP parsers continue to work on the signed APK. The APK Signing Block is designed for
+     * extensibility. For example, a future signature scheme could insert its signatures there as
