+Customize the Sidebar
+---------------------
+
+To change the contents of the sidebar, create a custom HTML template and specify
+it in ``conf.py``. For example, let's add a link to sponsor your project below
+the table of contents tree:
+
+.. code-block:: python
+
+   # Add any relative paths that contain templates.
+   templates_path = ["_templates"]
+
+   # Custom sidebar templates, must be a dictionary that maps document names
+   # to template names. "**" will apply the templates to all pages.
+   # The theme default is just searchbox and globaltoc.
+   html_sidebars = {"**": [
+       "searchbox.html",
+       "globaltoc.html",
+       "custom.html",    # Your template here
+   ]}
+
+Then in ``_templates/custom.html``:
+
+.. code-block:: html
+
+   <p>
+     Sponsor my project!
+     <a href="http://example.com">Here's the link</a>
+   </p>
