 ### Quickstart
 A Docker container of the component is hosted in the Microsoft Container Registry (MCR) and can be pulled by:
-~~~
+~~~console
 docker pull mcr.microsoft.com/iotedge/opc-plc:<See version.json>
 ~~~
 
 The tags of the container match the tags of this repository and the containers are available for Windows and Linux.
 
 Sample start command for Docker:
-~~~
+~~~console
 docker run --rm -it -p 50000:50000 -p 8080:8080 --name opcplc mcr.microsoft.com/iotedge/opc-plc:latest --pn=50000 --autoaccept --sph --sn=5 --sr=10 --st=uint --fn=5 --fr=1 --ft=uint --gn=5

 Sample start command for Windows:
-~~~

 Next, make your modifications and publish the opc-plc project in Visual Studio. Ensure that you have chosen "Self-Contained" as "Deployment Mode" and the correct "Target runtime" in the Visual Studio Publish configuration. Finally, run the `docker build` command in the folder you published to using the dockerfile of your configuration and target runtime.
