+About
+-----------
 
 PyFMI is a package for loading and interacting with Functional Mock-Up Units
 (FMUs) both for Model Exchange and Co-Simulation, which are compiled dynamic
-models compliant with the Functional Mock-Up Interface (FMI). See
- https://fmi-standard.org/ for more
-information.

+FMU Import Compliance
+-----------
+PyFMI is tested daily in several different ways:
+* Extensive external testing within the `Optimica Compiler Toolkit` (OCT) provided by [Modelon](https://help.modelon.com/latest/reference/oct/) using all models in Modelon Modelica libararies (35000+ models), exported as FMUs.
+* Unit tests from the `tests` directory. These use FMUs generated by
+  * OCT
+  * JModelica.org
+  * FMUs in the example directory are generated via <em>FMU SDK by Qtronic</em>, more information is available in related `README.txt` for these FMUs with proper license text. 
+* PyFMI is the default execution engine for [Modelon Impact](https://modelon.com/modelon-impact/).
+* Some testing with Dymola FMUs and FMUs from [FMI Cross Check](https://github.com/modelica/fmi-cross-check).
