The app will be generated under the folder target/dist.

Contributing

So you want to contribute? Great. We appreciate any help you're willing to give. Don't hesitate to open issues and/or submit pull requests.

Remember that this is the faucet we use at OKP4. This is why we may have to refuse change requests simply because they do not comply with our internal requirements, and not because they are not relevant.
