Good free resources for learning set theory

Question

I'm looking to learn set theory. My coding history has been primarily practical and I'd like to move more into the theory side of things. I think I understand the basic concepts of set theory but I know nothing about its applications, its notations, and operations you can perform on sets.

Any resources that could point me in the right direction would be great!
