-## Add New Translation Tags
-
- **Important**: If you add any new translation tags, they must first be added to the `messages_en_GB.properties` file. This ensures consistency across all language files.
- New translation tags **must be added** to the `messages_en_GB.properties` file to maintain a reference for other languages.
- After adding the new tags to `messages_en_GB.properties`, add and translate them in the respective language file (e.g., `messages_pl_PL.properties`).
-
 Make sure to place the entry under the correct language section. This helps maintain the accuracy of translation progress statistics and ensures that the translation tool or scripts do not misinterpret the completion rate.
