Adding "Custom Content" to your Home Page
Custom content can also be added in widget areas either by referencing an existing node, or by creating content within the widget area.
Existing node:
Clicking the "Existing node" link will take you to a form where you can reference an existing node. You will need to type the number of the existing node in the first text field. You can find that number in the URL at the top of the node as you are creating it or editing it. There are options to override the title of the node, leave existing node title, link the node title to the full node, allow comments and read more links and tell whether to show the entire node or just a teaser (build mode).
New custom content:
Clicking the “New custom content” link will take you directly to an editor where you can type in the content you desire to show in the widget.
Don’t forget to click the “Finish” button when you’re done typing.
