+# Dyolink overview
+
+Monorepo: `backend/` (NestJS + Prisma), `frontend/` (Next.js + next-intl), `infrastructure/` (Docker).
+
+## Domain
+
+- **CLINIC** orgs: patients, appointments, treatment, staff.
+- **LAB** orgs: cases, tasks, lab workflows.
+- Tab access: `TAB_*_READ` / `TAB_*_EDIT` in `backend/src/common/permissions.ts`. EDIT implies READ.
+
+## Agent behavior
+
+- Read `AGENTS.md` and file-scoped rules before large changes.
+- **Never commit or push** unless the user explicitly asks.
+- Prefer minimal diffs; reuse existing components and API patterns.
+- After cross-cutting changes: `backend` → `npm run build`; `frontend` → `npx tsc --noEmit`.
+
+## i18n
+
+All user-visible strings: `frontend/messages/en.json`, `fa.json`, `nl.json` — add keys to **all three**.
+
+## Treatment / appointment colors
+
+Treatment-type colors and labels: `components/shared/treatmentTypeDisplay.ts` + `catalog-type-colors.ts`. UI badges: `components/ui/treatment/TreatmentTypeBadge.tsx`.
