Changing the appearance of the document
You can change the styles in the template as your project develops. Do not make changes to styles in the master document or in any of the subdocuments—make those changes in the template.
To update the master document (and all of the subdocuments) with changes to the template, just open the master document. You will get two messages: first, to ask if you want to update all links; and second, if you want to apply the changed styles. Answer Yes to both of these messages.
