What to document, and how

Knowledge base (KB) articles — how to resolve common issues, written for the next person.

Asset & config records — what you have and how it's set up.

Write for your audience, keep it current, and use clear steps and screenshots. Great documentation reduces repeat tickets, speeds onboarding and feeds root cause analysis. It's a quiet superpower that gets you noticed.
