The Quarkus integration is a community extension that allows you to easily leverage Zeebe within your Quarkus environment.
Essentially, Quarkus provides a wrapper around the Zeebe Java Client, and is preconfigured with sensible defaults so you can get started with minimal configuration. Add a dependency, implement a worker, and add your credentials in your Quarkus project.
The integration also provides Quarkus developer services to start everything you need as Docker containers for local development. Zeebe-dev-monitor UI is also included as a developer service.
