 To connect to your application's MySQL database from your local machine, you may use a graphical database management application such as [TablePlus](https://tableplus.com). By default, the MySQL database is accessible at `localhost` port 3306 and the access credentials correspond to the values of your `DB_USERNAME` and `DB_PASSWORD` environment variables. Or, you may connect as the `root` user, which also utilizes the value of your `DB_PASSWORD` environment variable as its password.

+### MongoDB
+
+If you chose to install the [MongoDB](https://www.mongodb.com/) service when installing Sail, your application's `docker-compose.yml` file contains an entry for a [MongoDB Atlas Local](https://www.mongodb.com/docs/atlas/cli/current/atlas-cli-local-cloud/) container which provides the MongoDB document database with Atlas features like [Search Indexes](https://www.mongodb.com/docs/atlas/atlas-search/). This container uses a [Docker volume](https://docs.docker.com/storage/volumes/) so that the data stored in your database is persisted even when stopping and restarting your containers.
+
+Once you have started your containers, you may connect to the MongoDB instance within your application by setting your `MONGODB_URI` environment variable within your application's `.env` file to `mongodb://mongodb:27017`. Authentication is disabled by default, but you can set the `MONGODB_USERNAME` and `MONGODB_PASSWORD` environment variables to enable authentication before starting the `mongodb` container. Then, add the credentials to the connection string:
+
+```ini
+MONGODB_USERNAME=user
+MONGODB_PASSWORD=laravel
+MONGODB_URI=mongodb://${MONGODB_USERNAME}:${MONGODB_PASSWORD}@mongodb:27017
+```
+
+For seamless integration of MongoDB with your application, you can install the [official package maintained by MongoDB](https://www.mongodb.com/docs/drivers/php/laravel-mongodb/).
+
+To connect to your application's MongoDB database from your local machine, you may use a graphical interface such as [Compass](https://www.mongodb.com/products/tools/compass). By default, the MongoDB database is accessible at `localhost` port `27017`.
