I've been contracting at a company for a few years and things progressed from manually setting up servers (before I was involved) to using Ansible to provision multiple servers and now it's transitioning to a Kubernetes cluster and infrastructure as code from day 1 along with tomes of documentation to go with it. It really is worth it to go the extra mile and write comprehensive docs, even going as far as writing them in a conversational tone as if it's a blog post or a book. I'm really happy I found a company who treats documentation and workflows as first class resources. For a small team where only 1 person is working on this it helps eliminate the bus factor and it also makes it easier to have non-hardcore ops folks do code reviews on your IaC. Having them be able to get the gist of it with a little bit of background knowledge is so much better than nothing. All of this results in higher reliability of the services your company offers.
