 ## Installation

   This is your search results page. You can leave it empty of content, but set the `Template` meta tag to a template
   that loops through the pages and displays them. Your `search.md` might look like this:
-

   ```
   /*
   Title: Search results
   Template: search
   */
   ```

+- **Add a template file with the name defined in `search.md`.**
   Your template file (`search.twig` in the above example) should contain something like the following section, which
   lists the pages matching the search (substitute `paged_pages` for `pages` if using Pico-Pagination):

   If you simply want to make your search results page look like your standard page, you may want to edit your theme's `index.twig` file and change `{{ content }}` to `{% block content %} {{ content }} {% endblock %}`. This allows you to extend this base template and reuse all the other parts of it in your search results template:
 
   ```twig
   {% extends "index.twig" %}
-  
+
   {% block content %}
       {{ parent() }}
-

       <div class="SearchResults">
