I don't know how to use it. can you explain please?

I've done that, but I don't know from the part where it says,
"4. Re-run the commands with the updated tokens and cookies,
and run this command [ docker build -t twitter-likes-app ./app ]

what it mean by Re-run the commands?
I've tried many things that I can think of, but I only get errors..

Any update on this please? I have just tried it (August 2024) and it just shows error: 500.
