+===========================================
+Feature: #79225 - Plugin preview with Fluid
+===========================================
+
+See :issue:`79225`
+
+Description
+===========
+
+The page TSconfig to render a preview of a single content element in the Backend has been improved
+by allowing the rendering of plugins now as well.
+
+The following option allows to override the default output of a plugin via page TSconfig:
+
+.. code-block:: typoscript
+
+   mod.web_layout.tt_content.preview.list.example = EXT:site_mysite/Resources/Private/Templates/Preview/ExamplePlugin.html
+
+All properties of the tt_content record are available in the template directly.
+Any data of the flexform field `pi_flexform` is available with the property `pi_flexform_transformed` as an array.
+
+.. note::
+
+   If a PHP hook already is set to render the element, it will take precedence over the Fluid-based preview.
+
+.. index:: Backend, Fluid
