 ## 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.
+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 ROOT**.

 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.

 ## Bug Reports
 
-**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 app 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/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 with Android Studio. The IDE can be used for both app (Kotlin/Java) and native (C++/C) sources.
-- 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).
