-# Magisk Manager 
-You need to install CMake and NDK to build the zipadjust library for zip preprocessing
+# Magisk Manager
+This is one of the submodules used in Magisk. The project is licensed under GPL v3 (or newer).
+More info are written in the [Magisk Main Repo](https://github.com/topjohnwu/Magisk)
 
-## Pre-built Binaries
-Busybox (arm and x86) compiled by osm0sis (`libbusybox.so` under `app\src\main\jniLibs`)  
-Source and more info: [osm0sis' Odds and Ends](https://forum.xda-developers.com/showthread.php?t=2239421)
+## Building Notes
+You need to install CMake and NDK to build the zipadjust library.
+There are several files required to let Magisk Manager work properly, and they can be copied by using the build script in the [Magisk Main Repo](https://github.com/topjohnwu/Magisk). These files are: `magisk_uninstaller.sh`, `util_functions.sh`, `public.certificate.x509.pem`, and `private.key.pk8` under the `app/src/main/assets` folder.

-# This script can be placed in /cache/magisk_uninstaller.sh
-# The Magisk main binary will pick up the script, and uninstall itself, following a reboot
-# This script can also be used in flashable zip with the uninstaller_loader.sh
-# 
-# This script will try to do restoration with the following:
-# 1-1. Find and restore the original stock boot image dump (OTA proof)
-# 1-2. If 1-1 fails, restore ramdisk from the internal backup
-#      (ramdisk fully restored, not OTA friendly)
-# 1-3. If 1-2 fails, it will remove added files in ramdisk, however modified files
-#      are remained modified, because we have no backups. By doing so, Magisk will 
-#      not be started at boot, but this isn't actually 100% cleaned up
-# 2. Remove all Magisk related files
-#    (The list is LARGE, most likely due to bad decision in early versions
-#    the latest versions has much less bloat to cleanup)
