 ## Create docker container named LDD-TPR with graphical display, share folder `pwd`:
 
-    docker run --dns=129.69.252.252 -it --env HOST_UID=$(id -u $USER) --env HOST_GID=$(id -g $USER) --env DISPLAY=unix$DISPLAY --device /dev/dri --volume /tmp/.X11-unix:/tmp/.X11-unix:rw --volume $(pwd):/home/fenics/shared --name LDD-TPR quay.io/fenicsproject/stable:latest /bin/bash

 If you want the container do be automatically deleted after exiting add `--rm` option.
 
 
 If you have trouble with internet connection inside the container use
 
-        --dns=YOUR_DNS_SERVER
+  --dns=YOUR_DNS_SERVER
 
 
 ## Start LDD-TPR container and step into the container:
 
-    docker start LDD-TPR & docker exec -ti -u fenics LDD-TPR /bin/bash -l
+  docker start LDD-TPR & docker exec -ti -u fenics LDD-TPR /bin/bash -l
