How do I share Projects?

I am currently building a team to create games. I was wondering how we are going to create the game together and share the elements of the game. For example, if someone makes level 1, and I make level 2, how will we put them together? Do we send the file or what?
Thanks for the help :slight_smile:

Take a look at source control -> Source Control | Unreal Engine Documentation :slight_smile:

Thankyou mate
