In one sentence, describe what the following article is about:

If you don't have a Weebly account yet, you can create one for free at the Weebly website. You can use your Facebook or Google+ accounts to create your Weebly account. You'll find this to the right of your site name, next to the "Edit Site" button. If you are in the site editor, the "Upgrade" button can be found in the upper-right corner, next to the "Publish" button. There are three different membership options available, with different features. All three packages will allow your site to be found on search engines, come with unlimited pages and storage, offer free hosting, and remove the Weebly footer at the bottom of the page.  Starter - This is best for personal pages and blogs. You can sell up to ten different products, but Weebly takes a 3% cut. Pro - Pro gives you access to advanced site features such as HD Video, Audio, and Site Search. You can also sell more products (up to 25), and create membership groups for special access. Business - If you're planning on focusing your website on eCommerce, this is the option you want. You can sell an unlimited amount of products from your own domain with Weebly taking a 3% cut. Weebly charges you for a year of service at a time, so you won't actually be paying monthly. You'll need to enter a valid credit card or use your PayPal account to make the purchase. There is currently no way to get Weebly Pro, or any paid version of Weebly, for free.

Summary:
Log into your Weebly account. Click the "Upgrade" button on your Weebly Home page. Decide which package is right for you. Enter your payment details.
