If you have an ssh key set up in your DigitalOcean account, then that is the key set up on the root account. If not, you should have received a password email from DigitalOcean -- use that.
You might be more interested in installing our church app OneBody. You can do that by clicking the "Install on DigitalOcean" button in the readme here: https://github.com/churchio/onebody
but as for the app, I hit the IP and i just see the "DO Install Button" page. http://cl.ly/image/032E0s0S122I
is this expected?
thx for the awesome work btw, i am just so anxious to try it out, atleast for one of the church i know who could def use something like this.
