-# Amnezia
+# Amnezia VPN
+## _The best client for self-hosted VPN_
 
+[![Build Status](https://travis-ci.com/amnezia-vpn/desktop-client.svg?branch=master)](https://travis-ci.com/amnezia-vpn/desktop-client)
+
+Amnezia is a VPN client with the key feature of deploying your own VPN server on you virtual server.
+
+## Features
+- Very easy to use - enter your ip address, ssh login and password, and Amnezia client will automatically install VPN docker containers to your server and connect to VPN.
+- OpenVPN and OpenVPN over ShadowSocks protocols support. 
+- Custom VPN routing mode support - add any sites to client to enable VPN only for them.
+- Windows and MacOS support.
+- Unsecure sharing connection profile for family use.
+
+## Tech
+
+AmneziaVPN uses a number of open source projects to work:
+
+- [OpenSSL](https://www.openssl.org/)
+- [OpenVPN](https://openvpn.net/)
+- [ShadowSocks](https://shadowsocks.org/)
+- [Qt](https://www.qt.io/)
+- [EasyRSA](https://github.com/OpenVPN/easy-rsa) - part of OpenVPN
+- [CygWin](https://www.cygwin.com/) - only for Windiws, used for launching EasyRSA scripts
+- [QtSsh](https://github.com/jaredtao/QtSsh) - forked form Qt Creator
+- and more...
+
+## Development
+
+Want to contribute? Welcome!
+Use Qt Creator for fast developing.
+
+### Building sources and deployment
+Easiest way to build your own executables - is to fork project and configure [Travis CI](https://travis-ci.com/)
+Or you can build sources manually using Qt Creator. Qt >= 14.2 supported.
+Look to the `build_macos.sh` and `build_windows.bat` scripts in `deploy` folder for details.
