 The first command creates the empty database and sets the Character set to utf8. This is important at least when it comes to *fishbook*. The second row creates a user **foo** and grants that user all rights on all tables of **fish_book**. So far **foo** can only log in from the local machine. In order to grant access also from outsides you need to issue a second command:
 
 ```sql
+MariaDB [(none)]> CREATE USER 'foo'@'%' identified by 'password';
 MariaDB [(none)]> GRANT ALL ON fish_book.* TO 'foo'@'%' IDENTIFIED BY 'password';
 MariaDB [(none)]> FLUSH PRIVILEGES;
 ```
