That's not really a fair summary. The guide does explain how to make your site list well on Google, how to make it display correctly in the search results and how to select which pages are indexed, but the 22 pages also offer a wealth of simple to understand gems on how to make a site that is both useful to your visitors while being easy for Google and other search engines to analyse and index. There is little in here that is new to the experienced designer of well indexed sites, but there is a lot that people who have never really considered the search engines could learn from it.
Finally, they've kindly published it under the Creative Commons 3.0 Attribution Licence, so it would be possible for annotated versions to be produced, the guide is at http://www.google.com/webmasters/docs/search-engine-optimization-starter-guide.pdf.
