 ### Database (Prisma + PostgreSQL)
+- **Provider**: Neon (serverless PostgreSQL)
 - **Schema**: `prisma/schema.prisma` defines models: `Project`, `Tag`, `ExternalLink`, `ProjectTag`
 - **Enums**: `ProjectStatus` (ACTIVE/ARCHIVED), `LinkType` (WEBSITE/GITHUB/HUGGINGFACE/PAPER)
 - **Client singleton**: `src/lib/prisma.ts` exports Prisma client instance

   - `ExternalLink`: `@@unique([projectId, url])` (each project can't have duplicate URLs)
 - **Indexes**: `idx_project_status_createdAt`, `idx_project_slug`, `idx_tag_slug`, `idx_link_projectId`, `idx_link_type`, `idx_link_type_url` (composite for efficient URL-based deduplication)
 
+#### Neon Database Setup
+- **Dashboard**: https://console.neon.tech
+- **Connection String Format**: `postgres://[user]:[password]@[host]/[database]?sslmode=require`
+- **Vercel Integration**: Set `DATABASE_URL` environment variable in Vercel Dashboard (do NOT use `vercel.json` env references)
+- **Free Tier**: 0.5GB storage, 300 hours compute/month
+- **Run Migrations**: After deployment, run `pnpm prisma db push` or use Neon's SQL Editor to create tables

 ### Webhook Deduplication Strategy
 The webhook at `src/app/api/webhook/projects/route.ts` implements a **multi-level deduplication** strategy to prevent duplicate projects:
 1. **GitHub URL exact match** (highest priority) - via `ExternalLink` table using `idx_link_type_url` index
