Why do I say that? I've often said, read your manual. But I don't I don't read mine. It's not a novel, not interesting, book clubs don't recommend it. Don't read it.
About 70 years ago my highschool instructor offered this advice. "You don't have to remember everything. You need to know how to find everything". Reflecting on much of my life that's just what I've done.
Technical documents, manuals, ... You don't read them you discover where to find "everything". Start with the chapters, contents, features index, index.
So don't read, discover. Remember you eat and elephant bite by bite. Topic by topic.
