+# Neon Database Setup Guide
+
+This guide documents how we set up Neon.tech PostgreSQL for the Workflow Builder project.
+
+## What is Neon?
+
+Neon is a serverless PostgreSQL database that offers:
+- Free tier with 0.5 GB storage
+- Auto-suspend after 5 minutes of inactivity (saves costs)
+- Instant database branching (like git for databases)
+- Connection pooling built-in
+
+## Step-by-Step Setup
+
+### 1. Create a Neon Account
+
+1. Go to [https://console.neon.tech/](https://console.neon.tech/)
+2. Sign up using GitHub, Google, or email
+3. After signing in, you'll land on your dashboard
+
+### 2. Create a New Project
+
+When you first sign up, Neon automatically creates a project for you. If you need a new one:
+
+1. Click "New Project" in the dashboard
+2. Choose a project name (e.g., "workflow-builder")
+3. Select a region closest to you (e.g., "US East")
+4. Click "Create Project"
+
+### 3. Get Your Connection String
+
+1. From your project dashboard, click the "Connect" button (top right)
+2. A dialog appears with connection details
+3. Make sure "Connection pooling" is enabled (toggle should be ON)
+4. Click "Show password" to reveal the full connection string
+5. Copy the connection string - it looks like:
+   ```
+   postgresql://username:password@ep-xxx-xxx.region.aws.neon.tech/neondb?sslmode=require
+   ```
+
+### 4. Configure Environment Variables
+
+Create a `.env.local` file in your project root (this file is gitignored):
+
+```env
+# Database - Neon PostgreSQL
+DATABASE_URL=postgresql://your-connection-string-here
+
+# Authentication (generate with: openssl rand -base64 32)
+BETTER_AUTH_SECRET=your-generated-secret
+
+# Credentials Encryption (generate with: openssl rand -hex 32)
+INTEGRATION_ENCRYPTION_KEY=your-64-char-hex-string
+
+# App URLs
+BETTER_AUTH_URL=http://localhost:3000
+NEXT_PUBLIC_APP_URL=http://localhost:3000
+```
+
+Also copy to `.env` for Drizzle migrations:
+```bash
+cp .env.local .env
+```
+
+### 5. Push Database Schema
+
+Run the following command to create all tables:
+
+```bash
+pnpm db:push
+```
+
+This uses Drizzle ORM to push the schema defined in `lib/db/schema.ts` to your database.
+
+### 6. Start the Development Server
+
+```bash
+pnpm dev
+```
+
+Visit [http://localhost:3000](http://localhost:3000) - you should see the workflow builder!
+
+## How the Database Works in This Project
+
+### Technology Stack
+
+- **Drizzle ORM**: Type-safe database toolkit for TypeScript
+- **PostgreSQL**: The database engine (hosted on Neon)
+- **Better Auth**: Authentication library that stores users/sessions in the database
+
+### Database Schema
+
+The schema is defined in `lib/db/schema.ts` and includes:
+
+| Table | Purpose |
+|-------|---------|
+| `user` | User accounts (email, name, password hash) |
+| `session` | Active login sessions |
+| `account` | OAuth provider connections |
+| `verification` | Email verification tokens |
+| `workflows` | Workflow definitions (nodes, edges, config) |
+| `workflow_executions` | Workflow run history |
+| `workflow_execution_logs` | Detailed step-by-step logs |
+| `api_keys` | User API keys for programmatic access |
+
+### Database Commands
+
+```bash
+# Push schema changes to database (no migration files)
+pnpm db:push
+
+# Generate migration files (for production)
+pnpm db:generate
+
+# Open Drizzle Studio (visual database browser)
+pnpm db:studio
+```
+
+### Connection Flow
+
+1. App reads `DATABASE_URL` from environment
+2. `lib/db/index.ts` creates a connection pool using `postgres` driver
+3. Drizzle ORM wraps the connection for type-safe queries
+4. API routes and server components use `db` to query data
+
+## Troubleshooting
+
+### "database does not exist" Error
+
+Make sure your `DATABASE_URL` points to the correct database name (usually `neondb`).
+
+### Connection Timeout
+
+Neon auto-suspends after 5 min idle. First request after suspend has ~500ms cold start. This is normal.
+
+### Schema Push Fails
+
+1. Check `DATABASE_URL` is set correctly in both `.env` and `.env.local`
+2. Ensure your Neon project is active (not suspended)
+3. Try running `pnpm db:push` again
+
+## Security Notes
+
+- Never commit `.env` or `.env.local` files
+- These files are already in `.gitignore`
+- Rotate `BETTER_AUTH_SECRET` and `INTEGRATION_ENCRYPTION_KEY` if exposed
+- Neon connection strings include passwords - keep them secret!
