I am looking for some information on how to use WP as a CMS. I looked in the codex but did not find much specific about this (or if I did I did not recognize it). Is the way to do this through plug-ins? I see some nice sites that use WP as a CMS and am stumped as to how they do it. Like adding gallery or portfolio pages or having multiple layouts (pages with 3col and others with 2).
Is the codex the best place to find this info?
