Sure you can. Google’s entire algorithm is based on such a concept (if it’s tried and true, more people will link to it, thus increasing its rank).
In general, for any computer program, it’s worthwhile to google for its name and “tutorial” and see what comes up. That’s how I learned pretty much everything (HTML, photo editing, website creating) before I attended university. Plus, sometimes you find little communities, forums, where people are program experts and are willing to answer your questions for free.
