If you are a blogger and not a programmer then no - it ain't simple.
You are required to set up a 'Facebook App' which is some sort of programmer related entity. The help page is useless as it does not refer to or correlate with the boxes you're required to fill in in the facebook app page. For instance enter your url in the box - what box? The one saying App name that must be within 3 and 30 characters or the other two boxes, neither of which mention url?
