Devs, if you are working on a small team, or any size team really, documentation for systems architecture is important. I took over a small app that uses docker, Azure, App Center, and who knows what else. I’m not an expert in these technologies, so when something goes wrong, I am in a heap or trouble and take a long time to resolve.
If there was documentation on how systems were created and configured, that would help me tremendously. Be kind to team mates, and future team mates. Document what you do and why you do it. You owe it to the company you work for.
