 # Magisk Manager
-The project should be built with Android Studio version 2.2.0+  
-I use Java 8 features, which requires Jack compiler and it's only available in 2.2.0+  
-Also, you need to install CMake and NDK to build the zipadjust library for zip preprocessing
+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)
+
+## 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.
