 ### Local installation and operation
 The WebSocket Service is started from OS command line.   
 You can follow the progress in console output

 ## Docker support  
 ### Prerequisites  
 Make sure you have [git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) and [Docker desktop](https://www.docker.com/products/docker-desktop) installed.  
-
 ### Installation
 Clone/git pull the repo into any local directory   
-````
+```
   git clone https://github.com/rcemper/WebSocketIRIS.js.git   
-````
-  
+``` 
 Open the terminal in this directory, build and run the container:     
-
-````
+```
  docker-compose up -d   
-````    
+```   
 Next open a IRIS session in namespace USER and prepare the Globals for testing   
 a test program **ZSocket.MAC** is in subdirectory **src** of download directory

-
 Now activate your Node.js client  
 Have the external IP address and the SuperServerPort ready  !   
 default: localhost:1972 is just a placeholder

-
-
+```
+docker-compose exec wsock nodejs WebSocketIRIS.js <ip-adr>:<port>

+From IRIS terminal run
+```
