I haven't seen this posted anywhere (well, there's this Ajax post). Anyway, the answer is found here. . Essentially you just add some HTML code to your web page or blog.

I spent most of the week designing a new webpage for our bike club, Pearland Cycling Club. It can be found (temporarily at least) here. I'll be working on it for the next few weeks i guess (unless the committee changes its mind about this third complete rebuild of the website). It was a good opportunity to join the 'new age' of web design using CSS and HTML.
