I wrote a tutorial for NETTUTS that has been published:
Sweetcron is "The Automated Lifestream Blog Software". It is still in public beta, but is already a very nice blog software package. The beauty of Sweetcron is that new posts are created automatically from your activity elsewhere on the web. New photos on Flickr? Tweets on Twitter? Thumbs up on StumbleUpon? Blog posts on Tumblr? Add them all to your Sweetcron-powered site and they will appear on your site in minutes.
The tutorial goes all the way from installation to custom themes.
