Click on the pages menu in the left-hand sidebar, and then click all pages. This will bring up all the pages on your site. When you hover your mouse on the items in the list, a number of options will be displayed. Clicking on either the title or edit option will take you to the edit page for that item. In the editor you can highlight text you would like to edit. Then type in your new text to replace it, or click on what you would like to modify in the formatting bar, such as bold, italics, or alignment. Your content as displayed in the editor will give you a general idea of how it will look on your site. Click on the preview changes button before publishing or click the publish button to publish the changes.
