Version 0.1.0

- Use the SDL2 framework wholesale instead of manually extracting dylib and headers
- Run install_name_tool on the remaining dylibs so they use the correct load path
- Add generate-dmg.sh for creating packaged Mac builds

 # Moonlight PC
 
-[Moonlight PC](http://moonlight-stream.com) is an open source implementation of NVIDIA's GameStream, as used by the NVIDIA Shield, but built to run on Windows, Mac, and Linux.
+[Moonlight PC](http://moonlight-stream.com) is an open source implementation of NVIDIA's GameStream, as used by the NVIDIA Shield, but built to run on Windows, Mac, and Linux. This client is the successor to [Moonlight Chrome](https://github.com/moonlight-stream/moonlight-chrome) for streaming on PC.
 
 Moonlight also has mobile versions for [Android](https://github.com/moonlight-stream/moonlight-android) and  [iOS](https://github.com/moonlight-stream/moonlight-ios).
 
+See the [releases page](https://github.com/moonlight-stream/moonlight-qt/releases) for download links for Windows and Mac. For Linux, we're on [Flathub](https://flathub.org/apps/details/com.moonlight_stream.Moonlight).
+
+You can follow development on our [Discord server](https://discord.gg/6ERtzFY).
+
+ [![Windows AppVeyor Status](https://ci.appveyor.com/api/projects/status/glj5cxqwy2w3bglv/branch/master?svg=true)](https://ci.appveyor.com/project/cgutman/moonlight-qt/branch/master)
+ [![Mac and Linux Travis CI Status](https://travis-ci.org/moonlight-stream/moonlight-qt.svg?branch=master)](https://travis-ci.org/moonlight-stream/moonlight-qt)
+
+## Features
+ - Hardware accelerated video decoding on Windows, Mac, and Linux
+ - Supports streaming at up to 120 FPS on high refresh rate monitors
+ - Supports streaming at 720p, 1080p, 1440p, or 4K
+ - 5.1 surround sound audio
+ - HEVC support for better image quality at reduced bandwidth
+ - Keyboard and mouse support
+ - Gamepad support with SDL gamepad mappings
+
 ## Building
 1. Install the latest Qt SDK (and optionally, the Qt Creator IDE) from https://www.qt.io/download (select MSVC toolchain on Windows)
 2. Run `git submodule update --init --recursive` from within `moonlight-qt/`
