+            # If you *do* uncomment it, you will need to make sure that all the templates
+            # below are in the directory.
+            #
+            # Synapse will look for the following templates in this directory:
+            #
+            # * HTML page for a confirmation step before redirecting back to the client
+            #   with the login token: 'sso_redirect_confirm.html'.
+            #
+            #   When rendering, this template is given three variables:
+            #     * redirect_url: the URL the user is about to be redirected to. Needs
+            #                     manual escaping (see
+            #                     https://jinja.palletsprojects.com/en/2.11.x/templates/#html-escaping).
+            #
+            #     * display_url: the same as `redirect_url`, but with the query
+            #                    parameters stripped. The intention is to have a
+            #                    human-readable URL to show to users, not to use it as
+            #                    the final address to redirect to. Needs manual escaping
+            #                    (see https://jinja.palletsprojects.com/en/2.11.x/templates/#html-escaping).
+            #
+            #     * server_name: the homeserver's name.
