Tell us what’s happening:
The project instructions are missing. I found a YouTube which shows the original instructions such as where to look for the ipaddress and language headers.
the Request Header Parser Microservice instructions have not been changed at all this year (I checked github to see if anyone added or removed anything to the user stories, I found that they have remained the same all year).
They may even have remained since sometime in 2021 when they were written. (same goes for the other project)
Perhaps whatever you are looking at is even older than that. I would just based my work on what the official fcc site says I should do.
