You can edit the content on your page by clicking on Edit located at the top of your site on the blue Admin Bar. Once the editing interface loads, you can click into any editable area.
There are two different ways of adding content to your site. The first way deals with text, and the second is adding blocks. To add text to your page. Click the Edit button on the blue Admin Bar at the top of your site. The page refreshes into edit mode with blue bordered "editable regions". Click inside an editable region and start typing text, paste copied text, or select the "Add Block" icon to add a block.
Formatting Text
Here is how to format your text in Bold, Italic, or as a list (both numbered and un-numbered).
First, select (highlight) the text you would like to change. A box should pop up from the very text you have just selected. Select the icon for the option you desire. You can also use preformatted Styles by choosing the first option on the toolbar (usually "Normal").
Bullets or Numbered Lists:
To start a bulleted or numbered list, type the first item in your list and select it. Then, in the formatting popup, you will see two icons, one for bullets and the other for numbered lists. Select the one you want, and the numbered list begins. Pressing enter will create a new item. If you want, you can go back into the list and add an item, and press [Tab] to indent that item or [Shift] + [Tab] to outdent an item.
Linking Text
To link some text, start by selecting (highlighting) the text you want to convert into a link. Next, click the chain link icon button on the right of the contextual popup menu. This will change the contextual menu to show the linking options. On the left, the upload cloud icon button will let you drag and drop or browse for a file to upload and link to. The search bar searches for items already on your website (pages or previously uploaded assets) to link to. Using the Preview eye icon button allows you to test the link. Finally, use the Confirm checkmark icon button to finalize your link.
Blocks
Adding a "Block" lets you insert some pre-formatted, custom content.
Images
Add an Image to a page. This is one of the options in Blocks (above)
Publish
Once you have finished making changes, click the blue "Publish" button near the upper right corner of the page to save your work and make it available for the world to see.
