 There's another file (in the root directory of the theme) that is critical to the PDF generation process: prince-file-list.txt. This file simply iterates through the items in your sidebar and creates a list of links. Prince will consume the list of links from prince-file-list.txt and create a running PDF that contains all of the pages listed, with appropriate cross references and styling for them all.
 
+{{note}} If you have any files that you do not want to appear in the PDF, add <code>print: false</code> in the list of attributes in your sidebar. The prince-file-list.txt file that loops through the sidebar_doc.yml file to grab the URLs of each page that should appear in the PDF will skip over any items that have <code>print: false</code> in the item attributes. For example, you might not want your tag archives to appear in the PDF, but you probably will want to list them in the online help navigation. {{end}}

 ## 4. Customize your headers and footers
 
 Open up the css/printstyles.css file and customize what you want for the headers and footers. At the very least, customize the email address that appears in the bottom left.
