 # How to Run the Application
 
-The easiest way to run the application is to start the `main` method of the `Launcher` class (you'll find it in the `boostrap` module) from your IDE.
+You can run the application in Quarkus dev mode with the following command:
 
-You can use one of the following VM options to select a persistence mechanism:
+```shell
+mvn quarkus:dev
+```
+
+You can use one of the following system properties to select a persistence mechanism:
 
 * `-Dpersistence=inmemory` to select the in-memory persistence option (default)
 * `-Dpersistence=mysql` to select the MySQL option
 
-If you selected the MySQL option, you will need a running MySQL database. The easiest way to start one is to use the following Docker command:
+For example, to run the application in MySQL mode, enter:
 
 ```shell
-docker run --name hexagon-mysql -d -p3306:3306 \
-    -e MYSQL_DATABASE=shop -e MYSQL_ROOT_PASSWORD=test mysql:8.1
+mvn quarkus:dev -Dpersistence=mysql
 ```
 
-The connection parameters for the database are hardcoded in `RestEasyUndertowShopApplication.initMySqlAdapter()`. If you are using the Docker container as described above, you can leave the connection parameters as they are. Otherwise, you may need to adjust them.
-
+In dev mode, Quarkus will automatically start a MySQL database using Docker, 
+and it will automatically create all database tables.
