How to use this?

[ilyagr]

I'm not overly familiar with Terraform or Coder, so I'm a bit confused about how to use this repo.

I can do terraform init && terraform apply to create a server on Hetzner cloud. However, I'm not sure how to use it. Should I ssh into it? What username should I use? Will it use the ssh key I configured on Hetzner's console, or do I need to use the ssh key that's shown in Terraform's output (how?).

After/if I ssh into there, am I supposed to use the coder command-line tool to create a workspace? How do I then connect to it?

Thanks to anyone willing to answer naive questions!
