I am working on my first forum site. It is an ambitious attempt on my part because I am learning everything from scratch and rely mostly on samples from this forum and the web. Is there a documentation where I could find what the XenForo elements are? For example, what is a Category Strip, Navigation Tab, Header, Breadcrumb, Node, etc. I find it difficult to change settings for some elements because I don't know what they are called and where to change their settings. I searched for the documentation but I can't seemed to find it.
