+# Full game database dumps
+
+Put the upstream `world` and `hotfixes` dumps here before the first
+`docker compose up`. Both plain `.sql` and `.sql.gz` files are imported.
+
+The repository intentionally does not ship those datasets. Do not use
+`sql/base/dev`: those files contain empty developer schemas and are not a
+playable game database.
+
+If the database volume has already been initialized, add the dumps manually or
+recreate the volume explicitly with `docker compose down -v` (this deletes all
+database data).
