+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.

 ## Bug Reports
 
-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.
-
-**Only bug reports from Canary builds will be accepted.**
+**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 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
-- 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).
+For Magisk app crashes, record and upload the logcat when the crash occurs.
