 Inside code blocks you can also assign values to variables. Assignments use
-the ``set`` tag and can have multiple targets:
+the ``set`` tag and can have multiple targets.
+
+Here is how you can assign the ``bar`` value to the ``foo`` variable:
 
 .. code-block:: jinja
 
-    {% set foo = 'foo' %}
+    {% set foo = 'bar' %}
 
-    {% set foo = [1, 2] %}
+After the ``set`` call, the ``foo`` variable is available in the template like
+any other ones:
 
-    {% set foo = {'foo': 'bar'} %}
+.. code-block:: jinja
+
+    {# displays bar #}
+    {{ foo }}
 
+The assigned value can be any valid :ref:`Twig expressions
+<twig-expressions>`:
+
+.. code-block:: jinja
+
+    {% set foo = [1, 2] %}
+    {% set foo = {'foo': 'bar'} %}
     {% set foo = 'foo' ~ 'bar' %}
 
+Several variables can be assigned in one block:
+
     {% set foo, bar = 'foo', 'bar' %}
 
+    {# is equivalent to #}
+
+    {% set foo = 'foo' %}
+    {% set bar = 'bar' %}
+
 The ``set`` tag can also be used to 'capture' chunks of text:
 
 .. code-block:: jinja
 
     {% set foo %}
-      <div id="pagination">
-        ...
-      </div>
+        <div id="pagination">
+            ...
+        </div>
     {% endset %}
