+### Restoring db from dump
+
+Make an empty directory `sqlfiles` inside `data` folder which is in the repository root. Then, put the database dump files `now_test.sql`, `now_log_test.sql` and `now_view.sql` inside it.
+
+The initialization file (`restore_and_create.sql`) will then restore the database from these files when the container is first run, and also creates a user `'now_test'@'localhost'` with password `mariadb_password` for the database. The root users password will be `admin`.
+
+**Test that it worked:**
+
+`docker exec -it nowdb-db mariadb -u now_test -p`. Enter the password `mariadb_password`. 
+
+Select database with `USE now_test;`.
+
+Execute query: `select loc_name from now_loc where loc_name like "amb%";` which should print 9 rows if everything went right.
