 ### Software requirements
 
-- **Firefox 45**. This is a Firefox technical demo. So it might not work on your browser, if it doesn't implement what we're demoing. At the time of writing (December 2015), you need to download [Firefox Nightly](https://nightly.mozilla.org).
+- **Firefox 45**. This is a Firefox technical demo. So it might not work on your browser, if it doesn't implement what we're demoing. At the time of writing (January 2016), you need to download either [Firefox Developer Edition](https://www.mozilla.org/firefox/developer/) or [Firefox Nightly](https://nightly.mozilla.org).
 - Support for `canvas.captureStream` (this lets us get a video stream out of a canvas tag)
 - Support for `MediaRecorder` (this lets us encode a video file natively in the browser, without using additional JS libraries)
 
 Note: `MediaRecorder` is an upcoming API part of the [W3C MediaCapture](https://w3c.github.io/mediacapture-record/MediaRecorder.html) standard. `canvas.captureStream` is based on [another part of the same W3C standard](https://w3c.github.io/mediacapture-fromelement/#widl-HTMLCanvasElement-captureStream-CanvasCaptureMediaStream-double-frameRate). There's nothing proprietary or exclusive to Firefox here, other than the fact that other browsers do not implement these features yet. Once they do, these examples will work in them too!
 
 ## How to run the examples
 
-Just [download](https://github.com/mozdevs/mediarecorder/archive/gh-pages.zip) this repository and open `index.html` in your browser (see requirements above). It can't be easier!
