+## Database Seeding
+
+The seeding system provides a quick way to set up a functional environment for development, QA, and testing.
+
+### Safety Guard
+
+To prevent accidental data loss in production, seeding is blocked if `NODE_ENV=production`. If you explicitly need to seed a production-like environment (e.g., staging), you must set:
+
+```bash
+ALLOW_SEED=true
+```
+
+### Seeding Logic
+
+The `pnpm db:seed` script:
+1. **Infrastructure**: Upserts a default organization, project, and environments.
+2. **Users**: Creates default users with the following credentials (passwords are hashed):
+   - **Admin**: `admin@formbricks.com` / `password123`
+   - **Manager**: `manager@formbricks.com` / `password123`
+3. **Surveys**: Creates complex sample surveys (Kitchen Sink, CSAT, Draft, etc.) in the **Production** environment.
+4. **Responses**: Generates ~50 realistic responses and displays for each survey.
+
+### Idempotency
+
+By default, the seed script uses `upsert` to ensure it can be run multiple times without creating duplicate infrastructure. To perform a clean reset, use `pnpm db:seed:clear`.
