So maybe your problem is there is too much documentation that spans too far back and getting current relevant examples and docs is the hard part. The rails guides are kept current, but any popular framework that has been around for a while is going to have a similar problem. Rail's guides are pretty good compared to many others I've seen. Also there are books, courses, video series, and plenty of other resources that are up-to-date. There is no shortage of high quality up-to-date learning content available. It just may take some work to weed out some of the older content.
