I'm looking to connect a Salesforce Community with a Sitecore website via the CMS Connect feature.  But have been unable to get this working.  Please can I ask some basic questions:

1. What is a root path and how can I find it for Sitecore?

2. The Header & Footer path indicate a need to link to a "header.html" file.  But the website embeds the header in the Body section via CSS.  How can I put this set-up into CMS Connect

Very stuck.
