@neelchauhan Thank you for this document. I've done some minor editing. Note, that while "homelab" is technically OK in the tech world, almost every editor (including the one here in GitHub) shows it as a misspelling. Rather than fight with it, I've just changed it to "home lab" which is acceptable in all editors.
