 # Open Simulation Platform Software
-The open source software for co-simulation is built on a combination of technical solutions from the 
-Open Simulation Platform (OSP) initiators and other established industrial solutions. 
-The key working principle has been to use the best available technology and knowledge to meet the requirements for 
-the OSP to efficiently serve its purpose. The source code for all software except `kopl` is made available on 
-[GitHub](https://github.com/open-simulation-platform), free of charge, through the MPL 2.0 open source licence.
+The Open Simulation Platform ([OSP](http://open-simulation-platform.com)) project aims to create a maritime industry 
+ecosystem for co-simulation of “black-box” simulation models and “plug and play” configuration of systems. OSP relies 
+on the Functional Mock-up Interface ([FMI](https://fmi-standard.org/)) standard and the new OSP interface specification 
+([OSP-IS]()) for the simulation models interfaces. This facilitates the effective building of digital twins, which in 
+turn can be used to solve challenges with designing, building, integrating, commissioning and operating complex, 
+integrated systems. With common tools, standards and specifications OSP seeks to foster co-simulation 
+collaboration in the industry.

 The main benefit introduced with OSP-IS is the possibility to define FMU interconnections at a higher level, i.e. variable 
 group connections rather than scalar connections. Additionally, it enables automatic unit conversions and provides the a
