+Blockquote
+#######################################
+
+**Processor name:** ``blockquote``
+
+You can include an blockquote using the following text tag:
+
+.. literalinclude:: ../../../verto/tests/assets/blockquote/doc_example_basic_usage.md
+    :language: none
+
+Optional Tag Parameters
+***************************************
+
+- ``footer`` - Boolean flag to indicate whether the blockquote contains a footer.
+
+    - If given as ``true``, then the last line should start with ``- `` to show it's the footer.
+
+- ``source`` - Sets the ``cite`` parameter of the ``blockquote`` element.
+
+- ``alignment`` - Valid values are 'left', 'center', or 'right'. Providing one of these values Will add CSS classes to the image for alignment.
+
+The default HTML for a panel is:
+
+.. literalinclude:: ../../../verto/html-templates/blockquote.html
+   :language: css+jinja
+
+Using the following example tag:
+
+.. literalinclude:: ../../../verto/tests/assets/blockquote/doc_example_basic_usage.md
+   :language: none
+
+The resulting HTML would be:
+
+.. literalinclude:: ../../../verto/tests/assets/blockquote/doc_example_basic_usage_expected.html
+   :language: html
+
+Overriding HTML for Blockquote
+***************************************
+
+When overriding the HTML for blockquotes, the following Jinja2 placeholders are available:
+
+- ``{{ content }}`` - The text enclosed by the blockquote tags.
+- ``{{ footer }}`` - The provided footer text.
+- ``{{ alignment }}`` - The location to add extra CSS classes for alignment.
+- ``{{ source }}`` - The URL for the source.
+
+**Example**
+
+For example, providing the following HTML:
+
+.. literalinclude:: ../../../verto/tests/assets/blockquote/doc_example_override_html_template.html
+  :language: css+jinja
+
+with the following tag:
+
+.. literalinclude:: ../../../verto/tests/assets/blockquote/doc_example_override_html.md
+  :language: none
+
+would result in:
+
+.. literalinclude:: ../../../verto/tests/assets/blockquote/doc_example_override_html_expected.html
+  :language: html
