# Emulatorstation README
Bauen im Produktionsmodus:
- [ ] TODO Replace or update this README with instructions relevant to your application
./mvnw -Pproduction clean package -DskipTests
To start the application in development mode, import it into your IDE and run the `Application` class.
You can also start the application from the command line by running:
```bash
./mvnw
```
To build the application in production mode, run:
```bash
./mvnw -Pproduction package
```
## Getting Started
The [Getting Started](https://vaadin.com/docs/latest/getting-started) guide will quickly familiarize you with your new
Emulatorstation implementation. You'll learn how to set up your development environment, understand the project
structure, and find resources to help you add muscles to your skeleton — transforming it into a fully-featured
application.
