+You should now have two tables in your project. You can see them in

 ## Preparation
-Create a fresh UUID for the device ID. You can generate one
-[online](https://www.uuidgenerator.net/) or with the `uuidgen` command
-on Linux.
+Let's add a new device into the `devices` table. You can either
+specify a device ID yourself, or let the DB generate one for you.
 
-Add this device ID to the `devices` table. You can do this with the

+In the first case the SQL statement would look like this:

 INSERT INTO devices (id) VALUES ('<device-id>');
