Bottles and breast pump?!

This might be a totally dumb question. I mean it is but I just kinda wanna know what everyone else is doing! So I want to use dr brown bottles and I’m gonna pump but bottle feed. Obviously the bottles to the breast pump are different, so do I just pour what I pump in those into a dr brown bottle? Or do the bottles fit on the breast pump? Lol 😆 I don’t have any bottles yet to try it out. 🤦🏼‍♀️ please share your breast feeding/ pumping techniques! :)
