+## READ BEFORE OPENING ISSUES
+
+All bug reports require you to **USE CANARY 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 ROOT**.
+
+If you experience issues during installation, in recovery, upload the recovery logs, or in Magisk Manager, 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 Manager, dump the full `logcat` **when the crash happens**. **DO NOT** upload `magisk.log`.
+
+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.

 ## Introduction
 
-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.
+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.
 
-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 almost perfectly hide modifications within userspace. Note that since 2020.3, the CTS check of [Google's SafetyNet API](https://developer.android.com/training/safetynet/index.html) will **NOT** pass.
+Here are some feature highlights:
+
+- **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
 
-**Only reports using debug canary builds will be accepted.** \
-Access canary builds by upgrading to either canary Magisk Manager:
-- [Canary Manager (Release)](https://raw.githubusercontent.com/topjohnwu/magisk_files/canary/app-release.apk)
-- [Canary Manager (Debug)](https://raw.githubusercontent.com/topjohnwu/magisk_files/canary/app-debug.apk)
+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.
 
-For installation issues, upload both boot image and install logs. \
-For Magisk issues, upload boot logcat or dmesg. \
+**Only bug reports from Canary 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 Manager crashes, record and upload the logcat when the crash occurs.
 
-## Building Environment Requirements
+## Building and Development
 
--  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 (`$ANDROID_HOME/ndk-bundle`), or optionally specify a custom path `ANDROID_NDK_HOME`
--  (Windows Only) Python package Colorama: Install with `pip install colorama`, used for ANSI color codes
+- Magisk builds on any OS Android Studio supports. Install Android Studio and do the initial setups.
+- Clone sources: `git clone --recurse-submodules https://github.com/topjohnwu/Magisk.git`
+- Install Python 3.6+ \
+(Windows only: select **'Add Python to PATH'** in installer, and run `pip install colorama` after install)
+- Configure to use the JDK bundled in Android Studio:
+	- macOS: `export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home"`
+	- Linux: `export PATH="/path/to/androidstudio/jre/bin:$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
+- 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.
+- Optionally, set custom configs with `config.prop`. A sample `config.prop.sample` is provided.
+- To sign APKs and zips with your own private keys, set signing configs in `config.prop`. For more info, check [Google's Documentation](https://developer.android.com/studio/publish/app-signing.html#generate-key).
 
-## 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).
