To use it you have to install the Chrome extension from their site (using Google Chrome browser :)), then go to a youtube video. There you should create an account, you should do it with Facebook (otherwise it does not verify the account for some reason, weird I know), then you will see on the left side the Wildspark logo. Click it. Given that you connected with facebook, you should have received the 10 AMP. Hope it helps, cheers :)

To post, you go on a youtube video, and give AMP from 0.1 to how much you have in the wallet, by clicking the wildspark logo on the left side :). Then you can see your post on their site, wildspark.me. After others amp the same video you will be rewarded.
