 The HOST and PORT determine what address the ASReview server listens to. If this deviates from `localhost` and port 5000, and you run the front end separately, make sure the [front end can find the backend](#front-end-development-and-connectioncors-issues). The ALLOWED_ORIGINS key must be set if you run the front end separately. Put in a list all URLs that your front end uses. This can be more than one URL. Failing to do so will certainly lead to CORS issues.

 ### Converting an unauthenticated application into an authenticated one
 
 Start the application with authentication enabled for the first time. This ensures the creation of the necessary database. To avoid unwanted user input, shutdown the application.

 ## Database
 
 A database is needed to run the tests for authenticated versions of the app. In the `config` file a number of TOML configuration files exist that are used to create different versions of the app. The configuration files that create an authenticated version of the app lack the `SQLALCHEMY_DATABASE_URI` parameter! That parameter tells the backend where it can find the database. If that parameter is missing, the app will create and initialize a sqlite3 database automatically. After the test suite has been executed, this database will be removed. In case you would like to run all tests in a specific database, you need to provide the URI of the database yourself.

+If you want to use a [Postgresql database](https://www.postgresql.org/), read the DEVELOPMENT documentation
+how to set it up.
