-Configure ``switcher['url_template']``
---------------------------------------
-
-The switcher's links to other versions of your docs are made by combining the
-*version strings* from the JSON file with a *template string* you provide in
-``switcher['url_template']``. The template string must contain a placeholder
-``{version}`` and otherwise be a fully-resolved URL. For example:
-
-.. code:: python
-
-    html_theme_options = {
-        ...,
-        "switcher": {
-            "url_template": "https://mysite.org/en/version-{version}/",
-        }
-    }
-
-The example above will result in a link to
-``https://mysite.org/en/version-1.0/`` for the JSON entry for version
-``"1.0"``.
