+Inspired by Nextflow training: <https://training.nextflow.io/basic_training/containers/>
 
+In this hands on, we assume you already have an environment with docker installed, either locally, or remotely in a place such as github codespaces which we have made ready for you in this occation.
+
+Once the docker daemon is running you can run containers, we will start with the `hello-world` container, which is hosted on Docker Hub.
+
+In your command line, a docker container can be run with the following syntax: 
+```
+docker run <container-name>
+```
+
+Excercise:
+
+Run the publicly available `hello-world` container.
+
+Solution:
+
+```
+docker run hello-world
+```
+
+
+
+We notice that docker first tried to check if we had the container locally, as we did not, the online container repositories were checked.
+As the container was found, it was donwloaded, and run.
+
+We can also break down the step and only download an image without running it. This is done with the `pull` command using the following syntax:
+```
+docker pull <container-name>
+```
+
+To check which containers you have pulled, you can use `images` with the following syntax:
+```
+docker images
+```
+
+
+
+
+
+Excercise:
+
+Pull the publicly available `debian:bullseye-slim` container and verify it has been downloaded
+
+Solution:
+
+```
+docker pull debian:bullseye-slim
+docker images
+```
