How to make composer and gitlab friends?

Question

Composer

I'm trying to make composer and gitlab friends. On the Internet, I could only google something about a certain satis, with the help of which, if I understood correctly, you need to inform the composer about all gitlab repositories.
But how to tie it all together in a complex - still did not fully understand.
Tell me in which direction to dig?
