 ## Building a Docker image
 
 If you prefer a Docker container over building SymCC natively, just tell Docker
 to build the image after pulling the QSYM code as above. (Be warned though: the
-Docker image enables optional C++ support from source, so creating
-the image can take quite some time!)

+Alternatively, you can pull an existing image (current master branch) from
+Docker Hub:

+```
+$ docker pull eurecoms3/symcc
+$ docker run -it --rm symcc
+```

 This will build a Docker image and run an ephemeral container to try out SymCC.
 Inside the container, `symcc` is available as a drop-in replacement for `clang`,
 using the QSYM backend; similarly, `sym++` can be used instead of `clang++`. Now
