+This repository contains the *Essential* edition of Eclipse MOSAIC, which includes the runtime infrastructure, 
 the core libraries, and various implementations of simulators or couplings to existing ones. All features 
 included in this version of Eclipse MOSAIC are sufficient for most use-cases in the field of smart and connected mobility.
 Additional simulators and assessment features are provided by [Fraunhofer FOKUS](https://www.fokus.fraunhofer.de/go/asct) on a commercial basis.
