Trying to pull Docker image sethblack/python-seo-analyzer gives error "repository does not exist"

[alberto56]

Describe the bug

The README says this can be used with Docker:

docker run sethblack/python-seo-analyzer [ARGS ...]

However, that image does not exist.

To Reproduce

$ docker pull sethblack/python-seo-analyzer           
Using default tag: latest
Error response from daemon: pull access denied for sethblack/python-seo-analyzer, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

Expected behavior

Docker image should either exist, or the README should not contain Docker information.
