Creating Comprehensive Onboarding Documentation
Poor onboarding costs weeks of productivity and creates frustrated new hires. Comprehensive onboarding documentation helps new team members become productive contributors faster, reducing the burden on existing team members and improving retention.
Onboarding Challenges
| Without Good Docs | With Good Docs |
|---|---|
| Interrupt teammates constantly | Self-serve answers |
| Week 1 fighting setup | Day 1 working code |
| Tribal knowledge | Documented processes |
| Repeated explanations | One source of truth |
| Slow ramp-up | Faster productivity |

## How Data Flows
1. User interacts with React component
2. Component calls API via React Query
3. API validates request
4. Business logic in services
5. Database query via Prisma
6. Response formatted and returned
7. React Query updates cache
8. UI re-renders

Looking at a feature? Start with:
1. Frontend: apps/web/pages/[feature]/
2. API: apps/api/routes/[feature]/
3. Database: packages/db/schema/[feature].prisma

Best Practices
For Onboarding Docs
- Test regularly — Have each new hire follow exactly
- Update constantly — New hires update as they go
- Include "why" — Not just "how" but "why" we do things
- Be explicit — Don't assume prior knowledge
- Make it searchable — FAQ + glossary
Anti-Patterns
ONBOARDING DOC MISTAKES:
✗ Outdated setup instructions
✗ Missing troubleshooting
✗ No clear owner
✗ Too much too soon
✗ Only technical, no cultural
✗ No first tasks defined
✗ Never updated
✗ Scattered across many tools
