+Feature: #104114 - Command to generate Fluid schema files
+=========================================================
+
+See :issue:`104114`
+
+Description
+===========
+
+With Fluid Standalone 2.12, a new implementation of the XSD schema generator has
+been introduced, which was previously a separate composer package. These XSD files
+allow IDEs to provide autocompletion for ViewHelper arguments in Fluid templates,
+provided that they are included in the template by using the xmlns syntax:
+
+..  code-block:: html
+
+    <html
+        xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
+        xmlns:my="http://typo3.org/ns/Vendor/MyPackage/ViewHelpers"
+        data-namespace-typo3-fluid="true"
+    >
+
+A new CLI command has been defined to apply Fluid's new schema generator to TYPO3's
+Fluid integration. New Fluid APIs are used to find all ViewHelpers that exist in
+the current project (based on the composer autoloader). Then, TYPO3's configuration
+is checked for any merged Fluid namespaces (like `f:`, which consists of both
+Fluid Standalone and EXT:fluid ViewHelpers which in some cases override each other).
+
+After that consolidation, `*.xsd` files are created in `var/transient/` using another
+API from Fluid Standalone. These files which will automatically get picked up by
+supporting IDEs (like PhpStorm) to provide autocompletion in template files.
+
+
+Impact
+======
+
+To get autocompletion for all available ViewHelpers in supporting IDEs, the following
+CLI command can be executed in local development environments:
+
+..  code-block:: bash
+
+    vendor/bin/typo3 fluid:schema:generate
+
+.. index:: CLI, Fluid, ext:fluid
