+## Database Import
+
+The PostgreSQL database dump comes in the form of a `.dmp` file. The database must be empty prior to import.
+
+To import the database dump:
+
+1. Ensure PostgreSQL is running (e.g., via `docker-compose up -d`)
+2. Ensure the target database exists and is empty
+3. Import the dump using `pg_restore` from the host machine:
+
+```bash
+docker-compose exec -T db pg_restore -U postgres -d zkill -v < postgres-schema-latest.dmp
+```
