+# Docker images for basic testing
+
+This directory contains a [`Dockerfile`](Dockerfile) for creating Ubuntu
+containers with Python installed and very little else compared to the stock
+Ubuntu images from https://hub.docker.com/_/ubuntu/. These can be used for
+testing TensorFlow Quantum builds and tutorials in relatively isolated
+environments.
+
+The script [`create_docker_images.sh`](create_docker_images.sh) creates separate
+images with a range of Python versions (currently 3.9–3.12) installed in
+Ubuntu 22.04 and 24.04. The result is a set of images with names like
+`ubuntu22-cp39`, `ubuntu22-cp310`, etc. The script `create_docker_images.sh` is
+meant to be run simply like this:
+
+```shell
+./create_docker_images.sh
+```
+
+The configuration in `Dockerfile` runs a Bash shell as the last step if a
+container is not started with any other command to run. When combined with
+Docker's `-v` argument, you can easily run commands inside the container
+environment while accessing your TensorFlow Quantum source files. For example:
+
+```shell
+# The next cd command moves to the root of the source tree.
+cd $(git rev-parse --show-toplevel)
+docker run -it --rm --network host -v .:/tfq ubuntu24-cp312
+```
+
+will leave you with a shell prompt inside a basic Ubuntu 24.04 environment with
+Python 3.12 preinstalled and your local TensorFlow Quantum source directory
+accessible at `/tfq` from inside the container.
