+### What is the Cloudogu EcoSystem?
+The Cloudogu EcoSystem is an open platform, which lets you choose how and where your team creates great software. Each service or tool is delivered as a Dogu, a Docker container. Each Dogu can easily be integrated in your environment just by pulling it from our registry. We have a growing number of ready-to-use Dogus, e.g. SCM-Manager, Jenkins, Nexus, SonarQube, Redmine and many more. Every Dogu can be tailored to your specific needs. Take advantage of a central authentication service, a dynamic navigation, that lets you easily switch between the web UIs and a smart configuration magic, which automatically detects and responds to dependencies between Dogus. The Cloudogu EcoSystem is open source and it runs either on-premises or in the cloud. The Cloudogu EcoSystem is developed by Cloudogu GmbH under [MIT License](https://cloudogu.com/license.html).
