[Idiom] learn the ropes

[Nastya_Bashkina]

Good evening!
I want to use idiom "learn the ropes", but I can't right use it.
Could you say me how it can be used in the such context:
He found a job and learned the ropes of the deliveryman profession.
Thank you for your attention.

It means, as your example suggests, to learn the job. Use a search engine to find the origin.
