I had a docker container from docker images(https://github.com/Slicer/SlicerDocker) and (https://hub.docker.com/r/slicer/slicer-notebook). And I want to use the extension slicerRT, but I don’t know how to install SlicerRT in slicerDocker container. I have tried install.sh (https://github.com/Slicer/SlicerDocker/blob/master/slicer-notebook/install.sh), which doesn’t work. Someone could help me? Thanks in advance. 
Please explain what you did exactly and how it didn’t work (error messages, screenshots, anything).
