Add website link to repo's homepage

Here's an example of another repo using this feature:

Thanks for making this great software :)

@jffaust Howdy! Apologies for the delayed response - forgot about these discussion threads - but I think that's a great idea. Will take care of it right away, and thank you for your kind words. Have an awesome day!
