+#### Choose What Database Engine You Will Use
+
+This app is designed to use an SQLite database by default.
+You can set it up to use a MySQL database by configuring the environment variables accordingly.
+If your database is being hosted remotely, make sure the MySQL database has the proper authentication for the user from a remote server.
+Alternatively, you can also use the second `docker-compose-mysql.yml` file which provides a MySQL database as part of the cluster.
+To use the second `docker-compose-mysql.yml` file, use the following command at the last step of the installation:
+
+```sudo docker compose -f docker-compose-mysql.yml up```
+
 #### Populate Environment Variables
 
 Configuration values for the app are stored in the environment variables file.
