See page three of the PDF:
The Developer Notes display on the detail page for each content area you create in PowerCMS. These notes provide a line of code that will need to be added to any page in your site that is to display this PowerCMS content.
1. In PowerCMS, click View/Edit Content.
2. Click View on the desired content area.
3. Developer Notes are listed at the bottom of the page.
Note: The Developer Notes are dynamically generated based on your website’s site root. In order for them to work, the page that the code is inserted to, must reside within the same site as PowerCMS.
