 ### Filter Usage Examples

 Twig templates can have significant whitespace that affects the rendered output. This implementation supports the following mechanism for controlling whitespace:
 
+### Apply Tag
+
+The `apply` tag allows you to apply a filter to an entire block of template content:
+
+```twig
+{% apply upper %}
+    This text will be converted to uppercase.
+    {{ variable }} will also be uppercase.
+{% endapply %}
+```
+
+This is particularly useful for:
+- Applying transformations to both static and dynamic content
+- Handling complex HTML with the spaceless filter
+- Creating consistent text formatting across multiple lines
+- Processing content with custom filters
+
+Example usages:
+
+```twig
+{# Remove whitespace between HTML tags #}
+{% apply spaceless %}
+    <div>
+        <strong>Hello</strong>
+    </div>
+{% endapply %}
+
+{# Result: <div><strong>Hello</strong></div> #}
+
+{# Convert content to uppercase #}
+{% apply upper %}
+    Welcome, {{ user.name }}!
+{% endapply %}
+
+{# Replace content #}
+{% apply replace('e', 'a') %}
+    Hello there
+{% endapply %}
+{# Result: Hallo thara #}
+```
+
+### Verbatim Tag
+
+The `verbatim` tag allows you to output Twig syntax without it being processed:
+
+```twig
+{% verbatim %}
+    This {{ will not be processed }} as a variable.
+    {% if statements won't be executed %}
+{% endverbatim %}
+```
+
+This is useful when:
+- Displaying Twig syntax as part of documentation
+- Including template examples in your output
+- Working with JavaScript frameworks that use similar syntax (Vue.js, Angular, etc.)
+- Creating code examples that include Twig syntax
+
 ### Whitespace Control
 
 The whitespace control modifiers (`-` character) allow you to trim whitespace around tags:
