The Emacs Help System (opens in new tab)

Charlie Holland has a very nice contribution to June’s Emacs Carnival about underappreciated Emacs builtins. His post is about the Emacs help system and how you can use it to learn everything about Emacs. It’s a commonplace to say that Emacs is self-documenting but that’s little more than a slogan. Holland takes a long look at what that actually means.
