FAQ

How long should technical documentation be?

As long as needed for clarity. Quick starts: 5-10 min. Complete guides: comprehensive. Optimize for scannability.

Should I write docs before or after coding?

Both. Write specs before, polish docs after, update continuously as product evolves.

How do I keep documentation updated?

Version control docs with code, assign doc owners, review quarterly, automate what's possible.

What's more important: completeness or clarity?

Both critical. Complete but unclear = useless. Clear but incomplete = frustrating. Strive for both.

Should technical docs include code examples?

Absolutely. Examples are often more valuable than explanations. Show working code.

How technical should documentation be?

Match audience level. Beginners need basics, developers need details. Provide both tiers if possible.

Can AI fully replace technical writers?

No. AI assists and accelerates, but human review, domain expertise, and quality control are essential.
