+===========================================================
+Feature: #97778 - Support of language direction in ckeditor
+===========================================================
+
+See :issue:`97778`
+
+Description
+===========
+
+The configuration `contentsLangDirection` of the ckeditor is used to define the
+direction of the content. It is now filled by the direction defined in the site
+language of the current element.
+
+As fallback the Page TsConfig configuration :typoscript:`RTE.config.contentsLanguageDirection = rtl`
+can be used.
+
+
+Impact
+======
+
+The direction of the content inside the RichText element is defined by the
+language of record.
