+# Deployment Setup Guide
+
+This repository is configured for automatic deployment to Netlify using GitHub Actions.
+
+## Required GitHub Secrets
+
+To enable automatic deployment, you need to add these secrets in your GitHub repository:
+
+### 1. NETLIFY_AUTH_TOKEN
+1. Go to [Netlify](https://app.netlify.com)
+2. Navigate to **User Settings** → **Applications** → **Personal access tokens**
+3. Click **"New access token"**
+4. Give it a name (e.g., "JSON Viewer GitHub Actions")
+5. Copy the generated token
+6. In GitHub: **Settings** → **Secrets and variables** → **Actions** → **New repository secret**
+7. Name: `NETLIFY_AUTH_TOKEN`
+8. Value: Paste the token
+
+### 2. NETLIFY_SITE_ID
+1. In Netlify, go to your site dashboard
+2. Navigate to **Site settings** → **General** → **Site details**
+3. Copy the **Site ID** (format: `xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`)
+4. In GitHub: **Settings** → **Secrets and variables** → **Actions** → **New repository secret**
+5. Name: `NETLIFY_SITE_ID`
+6. Value: Paste the Site ID
+
+## How It Works
+
+- **Automatic Deployment**: Every push to `main` branch triggers a build and deployment
+- **Pull Request Previews**: PRs create preview deployments for testing
+- **Build Caching**: npm dependencies are cached for faster builds
+- **Security Headers**: Netlify.toml includes security and performance headers
+
+## Manual Deployment
+
+If you need to deploy manually:
+
+```bash
+npm run build
+netlify deploy --prod --dir=dist
+```
+
+## Troubleshooting
+
+### Build Fails
+- Check the GitHub Actions log for detailed error messages
+- Ensure all dependencies are listed in package.json
+- Verify Node.js version compatibility (using Node 20)
+
+### Deployment Fails
+- Verify both secrets are correctly set in GitHub
+- Check that NETLIFY_SITE_ID matches your Netlify site
+- Ensure NETLIFY_AUTH_TOKEN has proper permissions
+
+### Custom Domain
+- Configure custom domain in Netlify dashboard
+- Update DNS records to point to Netlify
+- SSL certificates are automatically generated
+
+## Support
+
+For issues with deployment, check:
+1. GitHub Actions workflow logs
+2. Netlify deployment logs
+3. Ensure secrets are properly configured
