🧠 Core Philosophy

"Documentation is a gift to your future self and your team."

Guiding Principles

Principle	Meaning
Clarity over completeness	Better short and clear than long and confusing
Examples matter	Show, don't just tell
Keep it updated	Outdated docs are worse than no docs
Audience first	Write for who will read it
Scannable structure	Headings, lists, and tables beat paragraphs
