How two people can work on the same project

Unity Engine
1

Hello,
A friend and I have been working on a game but we are both working on different projects and then sending eachother scenes/scripts when done with them. Is there a way to work on the same unity project? I used to keep my project in dropbox but that seemed unstable as I would sometimes get errors for seemingly no reason and would have to restart unity multiple times until they went away.
Thanks,
Ninnec

There is Unity Collaborate tool for that.

Also, consider use repositories, rather dropbox. Unless working on other visual assets like models and textures.
