You now know how to add items and sections to your site, upload images, and retrieve your orders. This page explains the rest of what you'll need to know to create your store. Once in your store Manager, select Simple or Regular edit.
Many stores have some text on the front page explaining what the site is about.
To add text to your front page, go to the front page and click on the Edit button. You'll see a field labelled Message. Enter some text there. If you want multiple paragraphs, just separate them with blank lines. But don't put too much text on your front page, if you can help it.
