Update README.md

[equivalent]

Overview

documentation is missing how to trigger "track download"

Thanks @equivalent - you're right this should be in the readme. Your second commit here (that adds the http call) isn't necessary though. Photo#track_download does the GET:

unsplash_rb/lib/unsplash/photo.rb

Lines 22 to 24 in 80efe97

	def track_download
	connection.get(links.download_location)["url"]
	end

As for the broken build I think that's just a configuration issue. I'll take a look.
