[html5] types of HTML content

[Brenton Strine]

I'm having a difficult time understanding the functionality and
relationships between the different content types. However, my only
resource right now is the W3 draft
(http://www.w3.org/TR/html5/content-models.html#kinds-of-content).
Does anyone know of a slightly less technical introduction to content
types or some sort of abridged, simplistic explanation of what they do
and how they work?

Thanks,

Brenton
