1. Start from recurring questions
The best first documentation topics are the ones people already ask repeatedly: how to deploy, where logs are, which database table matters, who owns credentials and how to validate a fix.
This creates immediate value and avoids a documentation project that never reaches the team.
- List the questions that stop support or deployment.
- Write short answers with links to evidence.
- Prefer useful maps over long theoretical documents.
- Record owners for domains, servers, databases and integrations.
- Review pages after incidents or handovers.
2. Maps before manuals
Before writing a large manual, create maps: system context, deployment flow, API endpoints, critical tables, integrations and backup routines. Maps help new contributors understand where to look.
A map can be incomplete and still useful if it points to the next evidence.
- Create a system context page with domains and services.
- Document deploy and rollback steps.
- List critical integrations and owners.
- Map where logs, backups and secrets are managed.
- Connect pages with links instead of duplicating everything.
3. Documentation needs a maintenance rhythm
Documentation becomes stale when it is separate from daily technical work. Tie updates to deploys, incidents, onboarding, architectural decisions and support learning.
A small living knowledge base is better than a perfect static document that nobody trusts.
- Update docs after production changes.
- Add incident lessons to the related operational page.
- Use templates for decisions, deploy notes and handovers.
- Keep outdated pages marked or removed.
- Review critical pages during maintenance routines.
