There is no step by step instructions for people that have their blog hosted by wordpress. I am assuming it works for those people as stated in the FAQ. It is very very vague how to get it done. It says the following in step one which I did not get past. "Install Jetpack either via the WordPress.org plugin directory, or by uploading the files to your server"
I don't have my own server and rely on WordPress. So I assume that I should be looking for a WordPress.org plugin directory. Have no clue where to find this. There is no instructions to say you will find this under Appearance->Widgets. Or something like that.
