+
+## Overview
+The arcore_camera_unity.zip file contains source code of the libarcore_camera_utility.so 
+C library. This library is used to create the Unity plugin for reading image pixels from 
+ARCore GPU texture.
+
+## Files Included
+- include/camera_utility.h : header file of the C API interface.
+- include/gl_utility.h : header file of GL utility functions.
+- include/texture_reader.h : header file of C++ API interface.
+- src/camera_utility.cc : implementation of the C API.
+- src/gl_utility.cc : implementation of GL utility functions.
+- src/texture_reader.cc : implementation of C++ API.
+
+## How to Build
+You can build the library by using Google Android NDK(https://developer.android.com/ndk/index.html). 
+Google Android NDK can be downloaded from this URL(https://developer.android.com/ndk/downloads/index.html).
