 A good starting point for building and running your own Docker images is to take an existing image from Docker Hub and run it locally on your computer.
 
-As a proof of concept for the company's applications, you decide to try running a sample image from Docker Hub. The image you've selected implements a basic .NET Core ASP.NET web app. Once you've established a process for deploying a Docker image, you'll be able to run one of your company's own web apps using Docker.
