 The application uses SQLite with a local database file stored in `data/app.db`. The database schema is automatically initialized on first run.

+## Deployment
+
+### Option 1: Docker Compose (Self-Hosted)
+
+```bash
+# Build and run
+docker compose up -d
+
+# View logs
+docker compose logs -f
+```
+
+Data is persisted in `./data/app.db` via Docker volume.
+
+### Option 2: Vercel + Turso (Cloud)
+
+1. Sign up at [Vercel](https://vercel.com) and [Turso](https://turso.tech)
+2. Connect your Git repository to Vercel
+3. Set environment variables in Vercel dashboard:
+   - `DB_TYPE=turso`
+   - `TURSO_URL=libsql://your-db.turso.io`
+   - `TURSO_TOKEN=your-token`
+4. Deploy automatically on git push
+
+See [docs/DEPLOYMENT.md](docs/DEPLOYMENT.md) for detailed instructions.

+# Deployment Guide
+
+This document describes how to deploy the Release Tracker application using two different approaches:
+
+1. **Docker Compose** (Self-Hosted) - Uses SQLite database
+2. **Vercel** (Cloud) - Uses Turso (serverless SQLite)
+
+## Quick Comparison
+
+| Feature | Docker Compose | Vercel |
+|---------|---------------|--------|
+| **Database** | SQLite (local file) | Turso (serverless SQLite) |
+| **Hosting** | Your own server | Vercel cloud |
+| **Cost** | Free (server cost only) | Free tier available |
+| **Setup complexity** | Medium | Low |
+| **Data control** | Full | Database hosted by Turso |
+| **Best for** | Single-user, internal tools | Multi-user, public access |
+
+---
+
+## Option 1: Docker Compose (Self-Hosted)
+
+### Prerequisites
+
+- Linux server (or macOS/Windows with Docker Desktop)
+- Docker and Docker Compose installed
+- (Optional) Intel Mac users: Docker Desktop supports linux/amd64 builds
+
+### Deployment Steps
+
+#### 1. Build and Run on Linux Server (Recommended)
+
+```bash
+# Clone or copy the project to your Linux server
+git clone <your-repo> release-tracker
+cd release-tracker
+
+# Build the Docker image
+sudo docker compose build
+
+# Run the container
+sudo docker compose up -d
+```
+
+#### 2. Build on Mac, Deploy to Linux
+
+If you're on an Intel Mac and want to build locally then deploy to Linux:
+
+```bash
+# Build for linux/amd64 platform
+docker build --platform linux/amd64 -t release-tracker:latest .
+
+# Save the image
+docker save release-tracker:latest | gzip > release-tracker.tar.gz
+
+# Copy to Linux server
+scp release-tracker.tar.gz user@linux-server:/tmp/
+
+# On Linux server, load and run
+ssh user@linux-server "cd /tmp && docker load < release-tracker.tar.gz"
+
+# Create docker-compose.yml on Linux server and run
+ssh user@linux-server "cd /opt/release-tracker && docker compose up -d"
+```
+
+#### 3. Data Persistence
+
+The SQLite database is stored in `./data/app.db` and mounted as a volume. To backup:
+
+```bash
+# Backup
+cp data/app.db backups/app.db.$(date +%Y%m%d)
+
+# Restore
+cp backups/app.db.20240101 data/app.db
+sudo docker compose restart
+```
+
+### Environment Variables
+
+Create a `.env` file in the project root:
+
+```bash
+# Database (SQLite is the only option for Docker)
+DB_TYPE=sqlite
+DATABASE_URL=file:./data/app.db
+
+# Next.js
+NODE_ENV=production
+NEXT_TELEMETRY_DISABLED=1
+```
+
+### Updating the Application
+
+```bash
+# Pull latest code
+git pull
+
+# Rebuild and restart
+sudo docker compose down
+sudo docker compose build --no-cache
+sudo docker compose up -d
+```
+
+---
+
+## Option 2: Vercel (Cloud)
+
+### Prerequisites
+
+- Vercel account (sign up at [vercel.com](https://vercel.com))
+- Git repository (GitHub, GitLab, or Bitbucket)
+- Turso account (sign up at [turso.tech](https://turso.tech))
+
+### Step 1: Set Up Turso Database
+
+1. Install Turso CLI:
+   ```bash
+   curl -sSfL https://get.tur.so/install.sh | bash
+   ```
+
+2. Login to Turso:
+   ```bash
+   turso auth login
+   ```
+
+3. Create a database:
+   ```bash
+   turso db create release-tracker
+   ```
+
+4. Get the database URL:
+   ```bash
+   turso db show release-tracker
+   ```
+   Copy the "LibSQL URL" (looks like: `libsql://release-tracker-username.turso.io`)
+
+5. Create an authentication token:
+   ```bash
+   turso db tokens create release-tracker
+   ```
+   Save this token securely.
+
+6. (Optional) Run migrations:
+   ```bash
+   # Set environment variables temporarily
+   export DB_TYPE=turso
+   export TURSO_URL=libsql://your-database-url
+   export TURSO_TOKEN=your-token
+   
+   # Push schema to Turso
+   npx drizzle-kit push
+   ```
+
+### Step 2: Deploy to Vercel
+
+1. **Connect Repository**:
+   - Go to [vercel.com](https://vercel.com)
+   - Click "Add New Project"
+   - Import your Git repository
+
+2. **Configure Build Settings**:
+   - Framework Preset: Next.js
+   - Build Command: `npm run build`
+   - Output Directory: `.next`
+
+3. **Set Environment Variables**:
+   In the Vercel dashboard, go to Project Settings → Environment Variables, add:
+
+   | Variable | Value |
+   |----------|-------|
+   | `DB_TYPE` | `turso` |
+   | `TURSO_URL` | Your Turso database URL |
+   | `TURSO_TOKEN` | Your Turso auth token |
+
+4. **Deploy**:
+   - Click "Deploy"
+   - Vercel will build and deploy automatically
+
+### Updating on Vercel
+
+Simply push to your Git repository:
+
+```bash
+git push origin main
+```
+
+Vercel will automatically rebuild and redeploy.
+

+
+## Local Development
+
+### Using SQLite (Default)
+
+```bash
+# Copy example env file
+cp .env.local.example .env.local
+
+# Install dependencies
+npm install
+
+# Run development server
+npm run dev
+```
+
+### Using Turso (Optional, for testing)
+
+```bash
+# Copy example env file and edit
+cp .env.local.example .env.local
+
+# Edit .env.local:
+DB_TYPE=turso
+TURSO_URL=libsql://your-database-url
+TURSO_TOKEN=your-token
+
+# Run development server
+npm run dev
+```
+
+---
+
+## Troubleshooting
+
+### Docker Issues
+
+**Issue**: Container fails to start with permission errors  
+**Solution**: The container runs as root (uid=0, gid=0) by default. If you have permission issues:
+
+```bash
+# Fix data directory permissions
+sudo chown -R 0:0 ./data
+sudo chmod -R 755 ./data
+```
+
+**Issue**: Database file is locked  
+**Solution**: Stop the container, remove the lock files, and restart:
+
+```bash
+sudo docker compose down
+rm -f data/*.db-wal data/*.db-shm
+sudo docker compose up -d
+```
+
+### Vercel Issues
+
+**Issue**: Build fails with database errors  
+**Solution**: Ensure environment variables are set in Vercel dashboard (not just in `.env.local`)
+
+**Issue**: Data doesn't persist between deployments  
+**Solution**: This is expected with SQLite on Vercel. You must use Turso for persistence.
+
+### Turso Issues
+
+**Issue**: Connection refused or timeout  
+**Solution**: Check your `TURSO_URL` and `TURSO_TOKEN` are correct. Turso databases may sleep after inactivity on free tier.
+
+---
+
+## Architecture Notes
+
+### Database Abstraction
+
+The application uses a database factory pattern (`src/lib/db/index.ts`) that automatically selects the appropriate database driver based on the `DB_TYPE` environment variable:
+
+- `DB_TYPE=sqlite`: Uses `better-sqlite3` driver with local file
+- `DB_TYPE=turso`: Uses `@libsql/client` driver with Turso
+
+Both use the same Drizzle ORM schema, so no code changes are needed when switching between them.
+
+### Data Migration Between Environments
+
+To migrate data from local SQLite to Turso:
+
+1. Export from SQLite:
+   ```bash
+   sqlite3 data/app.db .dump > backup.sql
+   ```
+
+2. Import to Turso:
+   ```bash
+   turso db shell release-tracker < backup.sql
+   ```
+
+Note: Some SQLite-specific syntax may need adjustment for Turso compatibility.
+
+---
+
+## Security Considerations
+
+### Docker Deployment
+
+- Container runs as root (uid=0) by design for simplicity
+- SQLite database file is owned by root
+- Ensure proper firewall rules on your server
+- Consider using HTTPS reverse proxy (nginx/traefik)
+
+### Vercel Deployment
+
+- Turso provides encryption at rest and in transit
+- Vercel provides HTTPS by default
+- Keep `TURSO_TOKEN` secure and rotate periodically
+
+---
+
+## Backup Strategy
+
+### Docker/SQLite
+
+```bash
+# Automated daily backup via cron
+0 2 * * * cp /opt/release-tracker/data/app.db /backups/app.db.$(date +\%Y\%m\%d)
+```
+
+### Vercel/Turso
+
+Turso provides automatic backups. You can also export manually:
+
+```bash
+turso db dump release-tracker > backup.sql
+```
+
+---
+
+## Support
+
+For issues specific to:
+- **Docker**: Check Docker logs with `docker compose logs`
+- **Vercel**: Check Vercel dashboard deployment logs
+- **Turso**: Check Turso dashboard or run `turso db inspect release-tracker`
