+# Deployment Guide
+
+## ⚠️ Vercel Deployment Warning
+
+**IMPORTANT**: The Next.js applications in this repository (`apps/web-evals` and `apps/web-roo-code`) are configured to **prevent accidental Vercel deployments**.
+
+### Vercel Prevention Measures
+
+1. **Automatic Vercel Monitoring Disabled**: Both applications have `automaticVercelMonitors: false` in their Next.js configuration
+2. **Vercel Ignore Files**: `.vercelignore` files are present in both applications to prevent deployment
+3. **Manual Override Required**: If you need to deploy to Vercel, you must manually remove these protections
+
+### Why These Protections Exist
+
+- Prevents accidental deployments during development
+- Avoids unintended resource usage on Vercel
+- Ensures intentional deployment decisions
+- Protects against misconfigured CI/CD pipelines
+
+### If You Need to Deploy to Vercel
+
+If you intentionally want to deploy to Vercel, you must:
+
+1. Remove or modify the `.vercelignore` files in the respective app directories
+2. Remove `automaticVercelMonitors: false` from the Next.js configuration files
+3. Configure your Vercel project settings appropriately
+
+### Alternative Deployment Options
+
+Consider these alternatives for deploying the Next.js applications:
+
+- **Docker**: Both applications can be containerized and deployed to any container platform
+- **Static Export**: Configure Next.js for static export if applicable
+- **Other Platforms**: Deploy to Netlify, Railway, or other hosting providers
+- **Self-hosted**: Deploy to your own infrastructure
+
+## Application-Specific Notes
+
+### web-evals
+
+- Located in `apps/web-evals/`
+- Next.js application for evaluation management
+- Vercel protections: `.vercelignore` + `automaticVercelMonitors: false`
+
+### web-roo-code
+
+- Located in `apps/web-roo-code/`
+- Next.js application for the main website
+- Vercel protections: `.vercelignore` + `automaticVercelMonitors: false`
+- Additional redirects configured for production domains
+
+## Development
+
+For local development, these protections do not affect your workflow:
+
+```bash
+# Start development servers
+cd apps/web-evals && npm run dev
+cd apps/web-roo-code && npm run dev
+```
+
+## Questions?
+
+If you have questions about deployment or need to modify these protections, please consult with the development team before making changes.
