git - setup new droplet as a remote for existing rails repository

I have an existing rails/git project that I’ve been using with both git and heroku remotes. I want to setup a remote for my new droplet to use instead of the heroku one. I’m trying to find the URL to create the remote:

git remote add docean ssh:// … ?

and the instructions to setup the Ubuntu/Rails instance in the droplet to be that remote.
