What part(s) of the article would you like to see updated?

The purpose of the string "PAT" in the username field when using this method of authentication isn't very clear.

You can clone the repository with a URL that includes the access token. Replace YOUR-VARIABLE with the name of the environment variable or secret you created.
git clone https://PAT:[email protected]/OWNER/REPO

It may be assumed that the username field must be set as "PAT", when it can actually take any value as long as it doesn't malform the URL.
There could also be confusion as to where the access token should be inserted.
Replacing "PAT" with a less ambiguous value like "USERNAME" may be more appropriate.
