+# Introduction
+SEAL (Simple Encrypted Arithmetic Library) is an easy-to-use homomorphic encryption 
+library, developed by researchers in the Cryptography Research group at Microsoft 
+Research. SEAL is written in standard C++17 and contains .NET Framework wrappers 
+for the public API. SEAL is licensed under the Microsoft Research License Agreement 
+and is free for research use (see LICENSE.txt).
+
+# System requirements
+Since SEAL has no external dependencies and is written in standard C++17 it is 
+easy to build on any 64-bit system. For building in Windows, SEAL contains a Visual 
+Studio 2017 solution file. For building in Linux and Mac OS X, SEAL requires either 
+g++-6 or newer, or clang++-5 or newer. Please see INSTALL.txt for installation 
+instructions using CMake.
+
+# Documentation
+The code-base contains examples written both in C++ and in C#. These examples are 
+heavily commented, serving as a self-contained short introduction to using SEAL.
+In addition, the .h files both in the C++ library and in the .NET wrapper library 
+contain detailed comments for the public API.
+
+To learn to use SEAL, we recommend looking at the example projects, as they 
+contain several detailed and thoroughly commented examples demonstrating most of 
+the basic features.
+

+Player, Gizem Cetin, Susan Xia, Peter Rindal, Kyoohyung Han, Zhicong Huang, and
