 * ``collapse_navigation`` Bool. With this enabled, you will lose the ``[+]`` drop downs next to each section in the sidebar.
-  This is useful for *very large* documents.
 * ``sticky_navigation`` Bool. This causes the sidebar to scroll with the main page content as you scroll the page.
-* ``navigation_depth`` Int. Indicate the max depth of the tree; by default, all levels are included.
+* ``navigation_depth`` Int. Indicate the max depth of the tree; by default, 4 levels are included;
+  set it to -1 to allow unlimited depth.
 * ``includehidden`` Bool. Specifies if the sidebar includes toctrees marked with the ``:hidden:`` option
 * ``titles_only`` Bool. If True, removes headers within a page from the sidebar.
 
+.. note::
+   
+   Setting ``collapse_navigation`` to False and using a high ``navigation_depth``
+   can cause projects with many files and a deep file structure to generate HTML files
+   that are significantly larger in file size and much longer compilation times.
