To deploy your process, take the following steps:

1. Decorate the `ProcessPaymentsApplication` class with `@Deployment(resources = "classpath:process-payments.bpmn")` in `ProcessPaymentsApplication.java`:

```java
@SpringBootApplication
@Deployment(resources = "classpath:process-payments.bpmn")
```

2. In Desktop Modeler, change the tax amount calculated to `total * 1.2` under **FEEL expression** and save your changes.

Re-run the application in your terminal with `mvn spring-boot:run` to see the process run. In Operate, note the new version `2` when filtering process instances, and the tax amount has increased for the most recent process instance.
