 You can pull any of the images from dockerhub using (for example)
 
-    docker pull dealii/dealii:v9.2.0-focal
+    docker pull dealii/dealii:v9.5.0-jammy
 
 after which you could run an interactive shell in it:
 
-    docker run -i -t dealii/dealii:v9.2.0-focal
+    docker run -i -t dealii/dealii:v9.5.0-jammy
 
 This will drop you in an isolated environment where you can experiment with deal.II.

+not the library itself. These images are helpful to compile your own version
+of deal.II. All images containing only deal.II dependencies can be found at:
