+Supporting Files (Notes)
+************************
+
+Supporting files, or notes, are any files stored in root folders that are not the Novel root folder.
+These files are intended for summaries and outlines of the various plot elements, characters, locations, and so on, of the novel.
+These are not required, but making at least minimal files for each such element, and add a tag to them, makes it possible to use the Outline View feature to see how each element intersects with each section of the novel itself, and add clickable cross-references between document in the editor and viewer.
+
+File Tags
+=========
+
+Each note file can have a tag associated with it,
+The format of a tag is ``@tag: tagname``, where tagname is a unique identifier.
+Tags can then be referenced in the novel files and will show up in the Outline View.
+
+The syntax highlighter will alert the user that the keyword is correctly used and that the tag is allowed, that is, the tag is unique.
+Duplicate tags should be detected as long as the index is up to date.
+
+The tag is the only part of these files that the application uses.
+The rest of the file is there for the writer to use in whatever way they wish.
+
+A note file can also reference other note files in the same way novel files do.
+When the note file is opened in the view pane, these become clickable links, making it easier to follow connections in the plot.
