initial setup of docker and docker-compose on digialocean

I registered an account and paid $5 using Paypal to get a droplet.

I registered my SSH key.

I wanted to run docker-compose. The instructions for

led me to
https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-18-04
where I logged in as root and set up a new user. I was then able to SSH in as the new user.

Then I completed the instructions for the Docker installation, including adding the non-root user to the docker group.

Finally I was able to complete the docker-compose instructions

Total time from initial registration to having docker-compose working: 25 minutes.
