+            ### Description of Changes
+
+            This Pull Request was automatically generated to synchronize updates to translation files and documentation. Below are the details of the changes made:
+
+            #### **1. Synchronization of Translation Files**
+            - Updated translation files (`messages_*.properties`) to reflect changes in the reference file `messages_en_GB.properties`.
+            - Ensured consistency and synchronization across all supported language files.
+            - Highlighted any missing or incomplete translations.
+
+            #### **2. Update README.md**
+            - Generated the translation progress table in `README.md`.
+            - Added a summary of the current translation status for all supported languages.
+            - Included up-to-date statistics on translation coverage.
+
+            #### **Why these changes are necessary**
+            - Keeps translation files aligned with the latest reference updates.
+            - Ensures the documentation reflects the current translation progress.
