Thanks for the PR @andrewfulton9!

This is looking good on a first pass but there's one thing I'd like to flag:

There's a good amount of overlap between this how-to guide and the AWS one on things that are general rather than provider specific (e.g. installing nic, first sign-in, GitOps repo, etc...). @khuyentran1401 opened an issue about this and I think we should address preferably before merging, or promptly after it to avoid drift and to keep things tidy. I'm not implying you should be the one to do that work and I'd like to have @khuyentran1401's input on how to best achieve this.

linking #680 for tracking of this

I left one suggestion on the title. The docs looks good from the scan. I'll let the engineers look at the technical aspects of the docs.

I updated the hetzner page to link to the deploy page introduced into #686, until that PR is merged and this branch is updated, the CI for this PR will fail
