To edit the introductory text on your ESP Website, select Introductory Text from the Design Studio dropdown.
The Introductory Text area is where you update the text that is shown on your home page. You can just type a headline and text, then click on the Save button.
There is a toolbar (hovering over the options in the toolbar will let you know what each tool will help you accomplish) across the top of the text area which enables you to customize your text. Below the text area, you can also click on the HTML button to edit the HTML coding of your Introductory Text.
