Terminology errors in docs

Be sure to turn any _carets_ into their _unicode characters_ for proper rendering.

I think you mean _angle brackets_ and _character references_ respectively. A caret is a completely different character altogether (it points upwards; brackets point sideways), and "unicode characters" is rather vague and ambiguous, not to mention that AFAIK character entity references like < and > have nothing to do with Unicode.
