 The folders in the tree view have no structural meaning other than they’re a way for you to organise your files into groups in whatever way suits you. They are not intended to represent chapters, but you can of course use them for that. If you do, know that you still need to define chapter headers in your structure so novelWriter knows where you want them.

 ## Linking Files and Notes
 
-You can link files and notes together by assigning tags to them, and then reference them from other files. The file class of a file determines which reference keywords apply to each file. For instance a file in the Characters root folder can be referenced using either the @char keyword or the @pov keyword.
+You can link project documents and notes together by assigning tags to the notes with the @tag keyword, and then reference them from other files using one of the many reference keywords. The file class of a file determines which reference keywords apply to each file. For instance a file in the Characters root folder can be referenced using either the @char keyword or the @pov keyword.
 
 If you want to see the content of the file the reference points to, you can click Ctrl+Enter with the cursor on top of the reference, and the view pane will show you the file. In the view pane, all references are clickable, so you can navigate further. At the bottom of the view pane, a list of files referencing the one your viewing will appear. This panel updates when you navigate, unless you make it sticky by clicking the sticky checkbox.
