+### Database
+Postgres and Sqlite databases are supported by the script natively. The included sqlite database will work out of the box. For connecting to sqlite, only the database file name is required, which is already provided in the .env.sample file. Hence, no changes to the database section will be required for sqlite.
+
+If you wish to use PostgreSQL database, change the value of the DATABASE key in the .env file to `postgres`. Make sure you also populate the rest of the values for the database. In case of postgres, the DB_FILE variable will be ignored.

 Have fun learning random words!
