Error response from daemon: manifest for sixeyed/nerd-dinner:latest not found

Good morning I’m new to docker.
I’ve installed docker on windows successfully and had pulled and tried the hello-world and microsoft/iis without a problem.
Now i’m trying to build an .net web application with the tutorial from elton stoneman’s Dockerizing Nerd Dinner.
I wanted to pull his image from dockerhub, but i got an error:
image
what can I do, to pull this image?

The answer is: docker pull sixeyed/nerd-dinner:part1
when you watch the site https://hub.docker.com/r/sixeyed/nerd-dinner/
and click the tags tab, you’ll see the tag name: part1
