+## Add translation
+
+1. Add language to appropriate resource in Transifex
+2. Ensure language is present in Django
+   - If not, update `cc_legal_tools/settings/base.py`
+3. Add objects for new language translation using the `add_objects` management
+   command.
+   - Examples:
+        ```shell
+        docker compose exec app ./manage.py add_objects -v2 --licenses -l tlh
+        ```
+        ```shell
+        docker compose exec app ./manage.py add_objects -v2 --zero -l tlh
+        ```
