Installing Docker

To follow along with this blog post you will need to have downloaded Docker Desktop.

• Mac: Download and install from https://hub.docker.com/editions/community/docker-ce-desktop-mac/
• Windows: Download and install from https://hub.docker.com/editions/community/docker-ce-desktop-windows/

Further details on installation, in case you get stuck can be found at: https://docs.docker.com/desktop/
