@axil Can you review?

resolved all discussions

@ayufan looks good! @tmaczukin one minor thing, you replaced 'Note' with 'Notice', although we use 'Note' everywhere else in the documentation, can you change it back?

OK, it seems that we use both Notice and Note in Runner's documentation. I thought we're using Notice only, but now I see that Note is used more times. I can change it back, and change this also in the second MR and rest will be updated in the future.

@axil Done!

LGTM! You have my blessing
