What is a Master Document?
A Master Document is one that is used as a "holder" for smaller documents. You can write the "front matter" in the master document and then add files which are, each, a separate part of the entire document.
You can edit the front matter, but not the inserted documents, as they are other files. It is best if both the Master Document and the files are based on the same template file.
