Copy and paste the code on your website in the HTML section. In some cases that means you'll need to press a "source" or HTML tab in order to properly paste code. This will also only work someplace that allows JavaScript.

However, it doesn't give you as many choices for customization, so it still may be worth your while to generate your own.
