 3. Add this line at the top of your template to load the sorting tags:
 
-       {% load sorting_tags %}
+    ```html
+    {% load sorting_tags %}
+    ```
 
 4. Decide on a variable that you would like to sort, and use the
    autosort tag on that variable before iterating over it:
 
-       {% autosort object_list %}
+    ```html
+    {% autosort object_list %}
+    ```
 
 5. Now, you want to display different headers with links to sort
    your objects_list:
 
     ```html
-        <tr>
-           <th>{% anchor first_name _("Name") %}</th>
-           <th>{% anchor creation_date _("Creation") %}</th>
-        </tr>
+    <tr>
+        <th>{% anchor first_name _("Name") %}</th>
+        <th>{% anchor creation_date _("Creation") %}</th>
+    </tr>
     ```
 
    The first argument is a field or an attribute of the objects list, and the
    second one (optional) is a title that would be displayed. The previous
    snippet will be rendered like this in French:
 
     ```html
-        <tr>
-            <th><a href="/path/to/your/view/?sort=first_name" title="Nom">Nom</a></th>
