+## Instructions
+
+### Install required codecs
+
+In this example, we'll be using x264 and opus as our video and audio codecs. Therefore, we need to make sure that these codecs are installed within our system. 
+
+Installation steps:
+
+* [x264](https://github.com/pion/mediadevices#x264)
+
+### Download vnc example
+
+```
+git clone https://github.com/pion/mediadevices.git
+```
+
+#### Compile vnc example
+
+```
+cd mediadevices/examples/vnc && go build
+```
+
+### Open example page
+
+[jsfiddle.net](https://jsfiddle.net/gh/get/library/pure/pion/mediadevices/tree/master/examples/internal/jsfiddle/audio-and-video) you should see two text-areas and a 'Start Session' button
+
+### Run the webrtc example with your browsers SessionDescription as stdin
+
+In the jsfiddle the top textarea is your browser, copy that, and store the session description in an environment variable, `export SDP=<put_the_sdp_here>`
+
+Run `echo $SDP | ./vnc`
+
+In Windows
+
+```powershell
+type sdp.txt| .\vnc.exe
+```
+### Input webrtc's SessionDescription into your browser
+
+Copy the text that `./webrtc` just emitted and copy into second text area
+
+### Hit 'Start Session' in jsfiddle, enjoy your video!
+
+A video should start playing in your browser above the input boxes, and will continue playing until you close the application.
+
+Congrats, you have used pion-MediaDevices! Now start building something cool

+# VNC Library for Go
+
+go-vnc is a VNC library for Go, initially supporting VNC clients but
+with the goal of eventually implementing a VNC server.
+
+This library implements [RFC 6143](http://tools.ietf.org/html/rfc6143).
+
+## Usage & Installation
+
+The library is installable via standard `go get`. The package name is `vnc`.
+
+```
+$ go get github.com/mitchellh/go-vnc
+```
+
+Documentation is available on GoDoc: http://godoc.org/github.com/mitchellh/go-vnc
