Tutorial Confusing from the Beginning

[rswetnam]

I just downloaded and installed Docker for Desktop and successfully launched it.

The tutorial says "Once you are done installing Docker, test your Docker installation by running the following:

$ docker run hello-world

Hello from Docker. This message shows that your installation appears to be working correctly. ...

Where do I do this? I try the cmd prompt and get the following message: "'$' is not recognized as an internal or external command,"

Being a bit more explicit for for a newbie would help.

Hi there, It's not about the tutorial, but it's about your knowledge base, specific in basic Linux command line.

'$' means a prompt for a 'normal' user, compare to '#' meaning for 'root' user, on a Linux system.

This means you don't need to type the '$' in to your cmd.

Back to basic Linux CLI things.
