How to setup the related content panel

1. First, associate an image with a page you want featured. To do this, put the page in Edit Mode and click on Properties. Then click on the Custom Attributes tab. Add the Page Thumbnail attribute. Pick the image you want to use. Hit save, exit Edit Mode and Publish.
2. Next, add a Page List block or Related Pages block (if you've purchased that add-on too) to the page you want the panel on. Choose the options you want for the pages to be displayed. Finally, check the Truncate Summaries box. The default 80 characters is a good number for that. Click Add to add the block to the page.
3. Now, click on the block that you just added and choose Custom Template from the menu. Then, select either Related Content Panel Dark or Related Content Panel Light from the drop down. Hit Update. Exit Edit Mode and Publish your changes.
