Long and short descriptions

In addition to all of the product data, there's the main content area, which is known as the long description:

And there's a panel beneath the product data for the Product short description:

Both of these appear on the product page. The short description is a 1-2 sentence description of the product and appears above the fold on most themes and browsers.

The long description is where you put every detail you can. Most users won't read this but users who do will want to see complete information. Feel free to add paragraphs of content. Break it up with bold phrases and bullet points. You can even add images and headings.
