positive.code: The first time you login, you will see a warning message asking if you want to add this host to your list of hosts. You should answer `yes`.
  
  You will now be able to explore your instance and perform various configuration and maintenance tasks. To exit from your login, type `exit`.
  
  
  
  
  === Create the Databases
  
negative.code: First, you need to edit the database properties. DB_SERVER should be set to the full name of the DB instance, as given in the *Connectivity and Security* panel (see above). The port number 3306 is required. DB_USER and DB_PASSWORD should be set to the administrator credentials you have chosen for the RDS instance.
  
  Second, you may optionally edit any Kill Bill properties that you need to change from the standard defaults. For more information see the https://docs.killbill.io/latest/userguide_configuration.html[Kill Bill Configuration Guide].
