Adding dokku to a Ghost droplet

I’ve set up a ghost droplet and pointed a domain to it.

Now I’d like to get a bit more serious and have my site under source control and use an editor other than nano to make changes to it.

I had a ghost blog working on heroku and then made the mistake of trying to update the version and as so many folks seemed to be down on heroku for hosting the ghost blog I found myself here. I want to keep a similar deployment pattern that I have there for another site ‘git push digitalocean master’ or something there abouts. What I actually do there is Bitbucket->Codeship->heroku

As I haven’t really added any content yet to the ghost blog would it be better for me to delete that droplet and start over with a dokku droplet and then add ghost to it?
