+
+## READ BEFORE OPENING ISSUES
+
+All bug reports require you to **USE DEBUG BUILDS**. Please include the version name and version code in the bug report.
+
+If you experience a bootloop, attach a `dmesg` (kernel logs) when the device refuse to boot. This may very likely require a custom kernel on some devices as `last_kmsg` or `pstore ramoops` are usually not enabled by default. In addition, please also upload the result of `cat /proc/mounts` when your device is working correctly **WITHOUT MAGISK**.
+
+If you experience issues during installation, in recovery, upload the recovery logs, or in Magisk, upload the install logs. Please also upload the `boot.img` or `recovery.img` that you are using for patching.
+
+If you experience a crash of Magisk app, dump the full `logcat` **when the crash happens**.
+
+If you experience other issues related to Magisk, upload `magisk.log`, and preferably also include a boot `logcat` (start dumping `logcat` when the device boots up)
+
+**DO NOT** open issues regarding root detection.
+
+**DO NOT** ask for instructions.
+
+**DO NOT** report issues if you have any modules installed.
+
+Without following the rules above, your issue will be closed without explanation.

-#### Building has been tested on 3 major platforms:
+#### This is not an officially supported Google product
 
-***macOS 10.12.5***  
-***Ubuntu 17.04 x64***  
-***Windows 10 Creators Update x64***  
+## Introduction
 
-#### Environment Requirements
+Magisk is a suite of open source software for customizing Android, supporting devices higher than Android 6.0.<br>
+Some highlight features:
 
-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  
+- **MagiskSU**: Provide root access for applications
+- **Magisk Modules**: Modify read-only partitions by installing modules
+- **MagiskBoot**: The most complete tool for unpacking and repacking Android boot images
+- **Zygisk**: Run code in every Android applications' processes
 
-#### Instructions and Notes
+## Downloads
 
-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.

+
+## Bug Reports
+
+**Only bug reports from Debug builds will be accepted.**
+
+For installation issues, upload both boot image and install logs.<br>
+For Magisk issues, upload boot logcat or dmesg.<br>
+For Magisk app crashes, record and upload the logcat when the crash occurs.
+
+## Translation Contributions
+
+Default string resources for the Magisk app and its stub APK are located here:
+
+- `app/core/src/main/res/values/strings.xml`
+- `app/stub/src/main/res/values/strings.xml`
+
+Translate each and place them in the respective locations (`[module]/src/main/res/values-[lang]/strings.xml`).
