 ### Configuring the database
 
 You can either use the database provided with ESS Community or you use a dedicated PostgreSQL Server. We recommend [using a PostgreSQL server](./docs/advanced.md#using-a-dedicated-postgresql-database) installed with your own distribution packages. For a quick set up, feel free to use the internal PostgreSQL database. The chart will configure it automatically for you by default.
