+# Why pion-WebRTC
+WebRTC is a powerful, but complicated technology. You can build amazing things with it comes with a steep learning curve though.
+Using WebRTC in the browser is easy, but outside the browser is more of a challenge. There are multiple libraries, and they all have
+varying levels of quality. Most are also difficult to build, and depend on libraries that aren't available in repos or portable.
+
+pion-WebRTC aims to solve all that! Built in native Go you should be able to send and receive media and text from anywhere with minimal headache.
+These are the design principals that drive pion-WebRTC and hopefully convince you it is worth a try.
+
+## Portable
+pion-WebRTC is written in Go and extremely portable. Anywhere Golang runs, pion-WebRTC should work as well! Instead of dealing with complicated
+cross-compiling of multiple libraries, you now can run anywhere with one `go build`
+
+## Simple API
+If you know how to use WebRTC in your browser, you know how to use pion-WebRTC.
+We try our best just to duplicate the Javascript API, so your code can look the same everywhere.
+
+If this is your first time using WebRTC, don't worry! We have multiple [examples](https://github.com/pions/webrtc/tree/master/examples) and [GoDoc](https://godoc.org/github.com/pions/webrtc)
+
+## Bring your own media
+pion-WebRTC doesn't make any assumptions about where your audio, video or text come from. You can use FFmpeg, GStreamer, MLT or just serve a video file.
+This library only serves to transport, not create media.
+
+## Safe
+Golang provides a great foundation to build safe network services.
+Especially when running a networked service that is highly concurrent bugs can be devastating.
+
+## Readable
+If code comes from an RFC we try to make sure everything is commented with a link to the spec.
+This makes learning and debugging easier, this WebRTC library was written to also serve as a guide for others.
+
+## Tested
+Every commit is tested via travis-ci Go provides fantastic facilities for testing, and more will be added as time goes on.
+
+## Shared libraries
+Every pion product is built using shared libraries, allowing others to review and reuse our libraries.
