Documentation Sync

The documentation site lives at apps/docs/ (Docusaurus 3, @homarr/docs).

When modifying user-facing code, you MUST also update the corresponding documentation:

• New integration → apps/docs/docs/integrations/<slug>/index.mdx + index.ts
• New widget → apps/docs/docs/widgets/<slug>/index.mdx + index.ts
• Changed API → apps/docs/docs/management/api.mdx
• New/changed env vars → apps/docs/docs/advanced/
• New CLI commands → apps/docs/docs/advanced/command-line/
• Auth changes → apps/docs/docs/advanced/ SSO pages
• New cron job → apps/docs/docs/management/tasks.mdx

Monorepo Commands

• pnpm dev — Next.js app only
• pnpm dev:docs — Docusaurus docs site only
• pnpm turbo build — build all packages
• pnpm turbo build --filter=@homarr/docs — build docs only
• pnpm turbo typecheck — typecheck all packages
• pnpm lint / pnpm format — oxlint / oxfmt

Code Style

• Lint: oxlint (not ESLint)
• Format: oxfmt (not Prettier)
• UI: Mantine (not Tailwind) — Tailwind is only used in docs app
• Icons: @tabler/icons-react
• Docs app can import from @homarr/definitions for shared types
