- Setup SSH Config in `~/.ssh/config`. The port listed here is usually correct, though you may want to verify that it is the same as the one listed in the output of `vagrant ssh-config dokku`
- Copy your SSH key via `cat ~/.ssh/id_rsa.pub | pbcopy` and paste it into the dokku-installer at http://dokku.me . Change the `Hostname` field on the Dokku Setup screen to your domain and then check the box that says `Use virtualhost naming`. Then click *Finish Setup* to install your key. You'll be directed to application deployment instructions from here.
You are now ready to deploy an app or install plugins.
