 # VIKTOR interaction with RFEM
 
 This sample application is made to showcase the interaction between VIKTOR and RFEM. It builds a model representing a truss, uses a VIKTOR worker running in an environment where RFEM is running with its web service enabled and visualizes the calculations inside the VIKTOR interface.

 ## The Worker
 
-To interact with RFEM using the VIKTOR application we use the VIKTOR worker. Some steps need to be taken to make it work. These steps are described [here](app/lib/README.md).
