Fixes issue 13

I think this is a reasonable change, but I dispute that it fixes #13, since that issue is really about the missing documentation for this library. The link you have used here doesn't provide any information about the library.

It may well be that no documentation will be published for this library, since the Uno WiFi is retired. In that case, we could use this Wayback Machine link:

The link you have used here doesn't provide any information about the library.

I agree with this.
Hence, changing link to- http://web.archive.org/web/20170812055940/http://www.arduino.org:80/learning/tutorials/boards-tutorials/content/arduino-uno-wifi-tutorial
which seems more relevant to the library.

Are all those redirection fail links under http://web.archive.org?

Are all those redirection fail links under http://web.archive.org?

If you mean the links to content on arduino.org that was never migrated to arduino.cc, from what I've seen so far, it does appear that all that content was archived on http://web.archive.org.

Oops. I meant "fall under" instead of "fail under".

Oh I see so they didn't migrate but are archived. Thanks for that.
