In HW1 the name of the file that need to be submittes is unclear.

On the one hand, it says it should be my username-hw1.pdf, on the other hand it is stated that the solution must include the names and id's of both students but is unclear as to how it should include them:
- In the notes in the moodle submission
- In the file name
- In an external text file
- Inside the pdf with the written answers
- Elsewhere
Thanks in advance
