In 'Create the pipeline' list, step 7 is skipped because a configuration is already imported and you can't select something else.
Just to follow the tutorial I deleted the azure-pipelines.yml in my fork.

If I created the default pipeline (with the YAML file in the repository) and then created a new pipeline I could complete step 7 as described.
