-# rmtPocketWatcher Setup Guide
-
-## What's Been Created
-
-✅ **Backend Scraper Service**
- Playwright-based scrapers for Eldorado and PlayerAuctions
- Automatic retry logic and error handling
- Scheduled scraping every 5 minutes
- Tracks all seller listings with platform, price, and delivery time
-
-✅ **Database Layer**
- PostgreSQL with Prisma ORM
- Three tables: VendorPrice, PriceIndex, ScrapeLog
- Stores all historical listings for trend analysis
- Indexed for fast queries
-
-✅ **API Layer**
- Fastify REST API with 6 endpoints
- WebSocket for real-time updates
- Filter by seller, platform, date range
- Historical price data
-
-✅ **Docker Setup**
- Docker Compose orchestration
- PostgreSQL container with health checks
- Backend container with auto-migration
- Volume persistence for database
-
-## Current Status
-
-The Docker Compose stack is building. This will:
-1. Pull PostgreSQL 16 Alpine image
-2. Build the backend Node.js container
-3. Install Playwright and dependencies
-4. Generate Prisma client
-5. Start both services
-
-## Once Build Completes
-
-### Check Status
-```bash
-# View logs
-docker-compose logs -f backend
-
-# Check if services are running
-docker ps
-```
-
-### Test the API
-```bash
-# Health check
-curl http://localhost:3000/health
-
-# Get latest prices (after first scrape)
-curl http://localhost:3000/api/prices/latest
-
-# Get lowest price
-curl http://localhost:3000/api/prices/lowest
-
-# Get price history
-curl "http://localhost:3000/api/index/history?range=7d"
-```
-
-### Monitor Scraping
-The backend will automatically:
- Scrape Eldorado and PlayerAuctions every 5 minutes
- Save all listings to the database
- Calculate and store the lowest price
- Log all scrape attempts
-
-Check logs to see scraping activity:
-```bash
-docker-compose logs -f backend | grep "scraping"
-```
-
-## Database Access
-
-### Using Prisma Studio
-```bash
-cd backend
-npm run db:studio
-```
-
-### Using psql
-```bash
-docker exec -it rmtpw-postgres psql -U rmtpw -d rmtpocketwatcher
-```
-
-## Stopping and Restarting
-
-```bash
-# Stop services
-docker-compose down
-
-# Start services
-docker-compose up -d
-
-# Rebuild after code changes
-docker-compose up --build -d
-
-# View logs
-docker-compose logs -f
-
-# Remove everything including data
-docker-compose down -v
-```
-
-## Environment Variables
-
-Edit `.env` or `docker-compose.yml` to configure:
-
- `SCRAPE_INTERVAL_MINUTES` - How often to scrape (default: 5)
- `SCRAPER_HEADLESS` - Run browser in headless mode (default: true)
- `PORT` - API server port (default: 3000)
- `DATABASE_URL` - PostgreSQL connection string
-
-## Next Steps
-
-1. **Wait for build to complete** (~2-5 minutes)
-2. **Verify services are running**: `docker ps`
-3. **Check first scrape**: `docker-compose logs -f backend`
-4. **Test API endpoints**: See examples above
-5. **Build Electron frontend** (coming next)
-
-## Troubleshooting
-
-### Backend won't start
-```bash
-# Check logs
-docker-compose logs backend
-
-# Restart backend
-docker-compose restart backend
-```
-
-### Database connection issues
-```bash
-# Check postgres is healthy

+# rmtPocketWatcher - Windows Build Instructions
+
+This document explains how to build rmtPocketWatcher for Windows distribution.
+
+## Prerequisites
+
+- Flutter SDK 3.22.3 or later
+- Windows 10/11 with Visual Studio Build Tools
+- PowerShell (for advanced build script)
+
+## Quick Build (Batch Script)
+
+For a simple build process, use the batch script:
+
+```cmd
+build_windows.bat
+```
+
+This will create:
+- `build\windows\standalone\rmtpocketwatcher.exe` - Standalone executable with all dependencies
+- `build\rmtPocketWatcher-Windows-Standalone.zip` - Distribution archive
+
+## Advanced Build (PowerShell Script)
+
+For more control and MSIX installer creation:
+
+```powershell
+# Release build (recommended for distribution)
+.\build_windows.ps1 -Release
+
+# Debug build (for development)
+.\build_windows.ps1 -Debug
+```
+
+This creates:
+- **Standalone Package**: Complete folder with all dependencies
+- **Portable Executable**: Single-file distribution (if possible)
+- **MSIX Installer**: Windows Store-style installer
+- **Distribution Archive**: ZIP file ready for sharing
+
+## Output Files
+
+After building, you'll find:
+
+### Standalone Distribution
+- `build\windows\standalone\` - Complete application folder
+- `build\windows\standalone\rmtpocketwatcher.exe` - Main executable
+- `build\windows\standalone\data\` - Flutter engine and assets
+- `build\windows\standalone\VERSION.txt` - Version information
+
+### Distribution Archives
+- `build\rmtPocketWatcher-Windows-v{version}.zip` - Full standalone package
+- `build\rmtPocketWatcher-Windows-Portable-v{version}.zip` - Portable version (exe only)
+
+### Installer (if created)
+- `build\windows\x64\runner\Release\*.msix` - Windows installer package
+
+## Distribution Options
+
+### Option 1: Standalone ZIP (Recommended)
+- Share the `rmtPocketWatcher-Windows-v{version}.zip` file
+- Users extract and run `rmtpocketwatcher.exe`
+- No installation required
+- All dependencies included
+
+### Option 2: Portable Executable
+- Share the `rmtPocketWatcher-Windows-Portable-v{version}.zip` file
+- Contains only the executable
+- Smallest download size
+- May require Visual C++ Redistributable on target machine
+
+### Option 3: MSIX Installer
+- Share the `.msix` file
+- Windows Store-style installation
+- Automatic updates support
+- Requires Windows 10 version 1809 or later
+
+## Testing
+
+To test the standalone build:
+
+```cmd
+cd build\windows\standalone
+rmtpocketwatcher.exe
+```
+
+## Troubleshooting
+
+### Build Fails
+- Ensure Flutter is properly installed: `flutter doctor`
+- Check Windows development setup: `flutter doctor -v`
+- Clean and retry: `flutter clean && flutter pub get`
+
+### MSIX Creation Fails
+- MSIX creation is optional and may fail on some systems
+- The standalone executable will still be created
+- Install Windows SDK if you need MSIX support
+
+### Runtime Issues
+- Ensure the `.env` file is present in the build directory
+- Check that all assets are included in the `data` folder
+- Verify Visual C++ Redistributable is installed on target machine
+
+## CI/CD Integration
+
+The build scripts are designed to work with the GitHub Actions workflow in `.gitea/workflows/release.yml`. The workflow automatically:
+
+1. Builds both standalone and portable versions
+2. Creates MSIX installer (if possible)
+3. Packages everything for release
+4. Uploads artifacts to the release
+
+## Manual Flutter Commands
+
+If you prefer manual control:
+
+```cmd
+# Basic build
+flutter build windows --release
+
+# Create MSIX (requires msix package)
+flutter pub get
+flutter pub run msix:create
+```
+
+Note: Manual builds won't include the packaging and organization provided by the build scripts.

+# Code Signing Certificate Guide for rmtPocketWatcher
+
+This guide explains how to create and use code signing certificates for your Windows application to eliminate security warnings and build user trust.
+
+## Quick Start
+
+1. **Create Certificate**: `.\create_certificate.ps1`
+2. **Build & Sign**: `.\build_windows.ps1 -Release`
+3. **Distribute**: Share the signed executables and optionally the public certificate
+
+## Certificate Types
+
+### Self-Signed Certificates (Free)
+- **Cost**: Free
+- **Trust Level**: Low (requires manual installation)
+- **Best For**: Development, internal distribution, open source projects
+- **Limitations**: Users see "Unknown Publisher" warnings initially
+
+### Commercial Certificates ($100-$500/year)
+- **Cost**: $100-$500 annually
+- **Trust Level**: High (automatically trusted)
+- **Best For**: Commercial software, wide distribution
+- **Providers**: DigiCert, Sectigo, GlobalSign, Entrust
+
+## Self-Signed Certificate Setup
+
+### Step 1: Create Certificate
+```powershell
+.\create_certificate.ps1
+```
+
+This creates:
+- `certificates/rmtPocketWatcher.pfx` - Private certificate (keep secure!)
+- `certificates/rmtPocketWatcher.cer` - Public certificate (for distribution)
+- `certificates/CERTIFICATE_INFO.txt` - Certificate details
+
+### Step 2: Build with Signing
+```powershell
+.\build_windows.ps1 -Release
+```
+
+This automatically:
+- Builds the application
+- Signs the executable with your certificate
+- Creates signed MSIX installer
+- Packages everything for distribution
+
+### Step 3: Manual Signing (if needed)
+```powershell
+.\sign_executable.ps1 -ExePath "path\to\your\app.exe"
+```
+
+## Certificate Installation for Users
+
+### Automatic Installation (Recommended)
+When users run your signed app for the first time:
+1. Windows shows "Unknown Publisher" warning
+2. User clicks "More info" → "Run anyway"
+3. Certificate is automatically added to their trusted store
+
+### Manual Installation (Optional)
+For organizations or power users:
+1. Distribute the `.cer` file alongside your app
+2. Users double-click the `.cer` file
+3. Click "Install Certificate"
+4. Choose "Local Machine" (requires admin) or "Current User"
+5. Select "Trusted Root Certification Authorities"
+6. Click "Next" and "Finish"
+
+## Commercial Certificate Setup
+
+### Step 1: Purchase Certificate
+Popular providers:
+- **DigiCert**: $474/year (EV), $239/year (OV)
+- **Sectigo**: $199/year (EV), $85/year (OV)
+- **GlobalSign**: $249/year (EV), $127/year (OV)
+
+### Step 2: Certificate Validation
+- **Organization Validation (OV)**: Business verification (1-3 days)
+- **Extended Validation (EV)**: Enhanced verification (1-5 days)
+- **Individual**: Personal ID verification
+
+### Step 3: Install Certificate
+1. Download certificate from provider
+2. Install to Windows Certificate Store
+3. Update build scripts with certificate details
+
+### Step 4: Update Configuration
+```yaml
+# pubspec.yaml
+msix_config:
+  certificate_path: path/to/commercial/cert.pfx
+  certificate_password: your_secure_password
+```
+
+## Security Best Practices
+
+### Certificate Storage
+- **Never commit** `.pfx` or `.p12` files to version control
+- Store certificates in secure, encrypted locations
+- Use strong passwords for certificate files
+- Backup certificates securely
+
+### Password Management
+- Use strong, unique passwords for certificates
+- Store passwords in secure password managers
+- Use environment variables in CI/CD pipelines
+- Rotate passwords regularly
+
+### CI/CD Integration
+```yaml
+# GitHub Actions example
+- name: Setup Certificate
+  run: |
+    echo "${{ secrets.CERT_BASE64 }}" | base64 -d > cert.pfx
+    
+- name: Sign Application
+  run: |
+    signtool sign /f cert.pfx /p "${{ secrets.CERT_PASSWORD }}" app.exe
+```
+
+## Troubleshooting
+
+### "SignTool not found"
+**Solution**: Install Windows SDK
+- Download from: https://developer.microsoft.com/windows/downloads/windows-sdk/
+- Or install Visual Studio with Windows development tools
+
+### "Certificate not valid for code signing"
+**Solution**: Ensure certificate has "Code Signing" usage
+```powershell
+# Check certificate usage
+Get-PfxCertificate -FilePath cert.pfx | Select-Object -ExpandProperty Extensions
+```
+
+### "Timestamp server unavailable"
+**Solution**: Try different timestamp servers
+- http://timestamp.digicert.com
+- http://timestamp.sectigo.com
+- http://timestamp.globalsign.com
+
+### "Access denied" when signing
+**Solution**: Run PowerShell as Administrator
+```powershell
+# Check if running as admin
+([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")
+```
+
+### Users still see warnings
+**Possible causes**:
+1. Certificate not properly installed
+2. Certificate expired
+3. System clock incorrect
+4. Antivirus interference
+
+## Certificate Lifecycle
+
+### Monitoring Expiration
+```powershell
+# Check certificate expiration
+$cert = Get-PfxCertificate -FilePath "certificates/rmtPocketWatcher.pfx"
+$daysUntilExpiry = ($cert.NotAfter - (Get-Date)).Days
+Write-Host "Certificate expires in $daysUntilExpiry days"
+```
+
+### Renewal Process
+1. **Self-signed**: Run `.\create_certificate.ps1 -Force`
+2. **Commercial**: Renew through certificate provider
+3. Update build scripts with new certificate
+4. Re-sign and redistribute applications
+
+### Migration to Commercial
+1. Purchase commercial certificate
+2. Update `pubspec.yaml` configuration
+3. Update build scripts
+4. Re-sign all distributed applications
+5. Notify users of the change
+
+## Cost-Benefit Analysis
+
+### Self-Signed Certificates
+**Pros**:
+- Free
+- Full control
+- Good for development/testing
+- Suitable for open source projects
+
+**Cons**:
+- Users see warnings initially
+- Requires user education
+- Not suitable for commercial distribution
+
+### Commercial Certificates
+**Pros**:
+- Immediate trust
+- Professional appearance
+- Better user experience
+- Required for some distribution channels
+
+**Cons**:

+# CI/CD Certificate Setup Guide
+
+This guide explains how to set up code signing certificates for automated builds in your CI/CD pipeline.
+
+## Prerequisites
+
+1. **Certificate Created**: Run `.\create_certificate.ps1` to create your certificate
+2. **Local Testing**: Verify signing works locally with `.\build_windows.ps1 -Release`
+
+## Step 1: Encode Certificate

+
+| Secret Name | Value | Description |
+|-------------|-------|-------------|
+| `CERT_BASE64` | Contents of `certificate_base64.txt` | Base64 encoded certificate |
+| `CERT_PASSWORD` | `rmtPocketWatcher2024!` | Certificate password |
+
+### For GitHub Actions:
+
+1. Go to repository "Settings" → "Secrets and variables" → "Actions"
+2. Click "New repository secret"
+3. Add the same secrets as above
+
+## Step 3: Security Cleanup
+
+**IMPORTANT**: After adding the secrets, delete the local files:
+
+```powershell
+Remove-Item certificate_base64.txt -Force
+```
+
+## Step 4: Verify Setup
+
+1. Push a change to trigger the workflow
+2. Check the build logs for:
+   - "✅ Certificate installed successfully"
+   - "✅ Executable signed successfully"
+   - "✅ MSIX installer signed successfully"
+
+## How It Works
+
+### Certificate Installation
+The workflow automatically:
+1. Decodes the base64 certificate
+2. Saves it as `certificates/rmtPocketWatcher.pfx`
+3. Uses it for signing during the build process
+
+### Signing Process
+The build script signs:
+- **Standalone executable**: `rmtpocketwatcher.exe`
+- **MSIX installer**: `*.msix` file
+
+### Environment Variables
+- `CERT_PASSWORD`: Used by signing scripts
+- `MSIX_CERTIFICATE_PASSWORD`: Used by MSIX creation
+
+## Troubleshooting
+
+### "Certificate not found" Error
+- Verify `CERT_BASE64` secret is set correctly
+- Check the base64 encoding is complete (no line breaks)
+
+### "Invalid certificate password" Error
+- Verify `CERT_PASSWORD` secret matches your certificate password
+- Default password is `rmtPocketWatcher2024!`
+
+### "SignTool not found" Error
+- This should not occur in GitHub/Gitea runners
+- Windows runners include Windows SDK by default
+
+### Unsigned Executables
+- Check workflow logs for certificate setup messages
+- Verify both secrets are set correctly
+- Ensure certificate is valid and not expired
+
+## Security Best Practices
+
+### Certificate Protection
+- Never commit `.pfx` files to version control
+- Use repository secrets for sensitive data
+- Regularly rotate certificate passwords
+
+### Access Control
+- Limit repository access to trusted contributors
+- Use branch protection rules
+- Require reviews for workflow changes
+
+### Monitoring
+- Monitor build logs for signing failures
+- Set up notifications for failed builds
+- Regularly verify certificate expiration dates
+
+## Commercial Certificate Migration
+
+When upgrading to a commercial certificate:
+
+1. **Obtain Certificate**: Purchase from DigiCert, Sectigo, etc.
+2. **Update Secrets**: Replace `CERT_BASE64` with new certificate
+3. **Update Password**: Change `CERT_PASSWORD` if different
+4. **Test Build**: Verify signing works with new certificate
+
+## Certificate Lifecycle
+
+### Monitoring Expiration
+Add this to your workflow to check certificate expiration:
+
+```yaml
+- name: Check Certificate Expiration
+  shell: pwsh
+  run: |
+    if (Test-Path "certificates\rmtPocketWatcher.pfx") {
+      $cert = Get-PfxCertificate -FilePath "certificates\rmtPocketWatcher.pfx"
+      $daysUntilExpiry = ($cert.NotAfter - (Get-Date)).Days
+      Write-Host "Certificate expires in $daysUntilExpiry days"
+      if ($daysUntilExpiry -lt 30) {
+        Write-Warning "Certificate expires soon!"
+      }
+    }
+```
+
+### Renewal Process
+1. Create new certificate (self-signed or commercial)
+2. Encode with `.\encode_certificate.ps1`
+3. Update `CERT_BASE64` secret
+4. Update `CERT_PASSWORD` if changed
+5. Test with a new build
+
+## Support
+
+For issues with certificate setup:
+1. Check workflow logs for detailed error messages
+2. Verify certificate validity locally first
+3. Test encoding/decoding process manually
+4. Consult the main Certificate Guide for certificate creation issues

+# Update System
+
+The rmtPocketWatcher Flutter app includes an automatic update checking system that monitors the Gitea repository for new releases.
+
+## How It Works
+
+1. **Automatic Checks**: The app checks for updates every 4 hours automatically
+2. **Manual Checks**: Users can manually check for updates using the refresh button in the title bar
+3. **Version Comparison**: Compares current app version (from pubspec.yaml) with latest release tag
+4. **Platform Detection**: Automatically detects the appropriate download asset for the current platform
+
+## Components
+
+### UpdateService
+- Fetches releases from Gitea RSS feed: `https://git.hudsonriggs.systems/LambdaBankingConglomerate/rmtPocketWatcher/releases.rss`
+- Parses XML/RSS format to extract release information
+- Compares version numbers and generates platform-specific download URLs
+
+### UpdateProvider
+- Manages update checking state and notifications
+- Stores last check time and dismissed updates in SharedPreferences
+- Provides reactive state for UI components
+
+### UpdateNotificationBanner
+- Shows a dismissible banner when updates are available
+- Displays version information and release details
+- Provides direct links to download or view release page
+
+## Configuration
+
+The system is configured to work with your Gitea repository structure:
+- Repository: `LambdaBankingConglomerate/rmtPocketWatcher`
+- RSS Feed: `https://git.hudsonriggs.systems/LambdaBankingConglomerate/rmtPocketWatcher/releases.rss`
+- Release tags should follow semantic versioning (e.g., `v1.0.0`, `v1.2.3`)
+- Expected asset naming convention:
+  - Windows: `rmtPocketWatcher-Windows-v{version}.zip`
+  - Android: `rmtPocketWatcher-Android-v{version}.apk`
+  - Future platforms can be added with similar naming patterns
+
+## Usage
+
+The update system is automatically initialized when the app starts:
+
+```dart
+// In HomeScreen initState
+context.read<UpdateProvider>().initialize();
+context.read<UpdateProvider>().startPeriodicChecks();
+```
+
+Users will see:
+1. A notification banner when updates are available
+2. An update icon in the title bar (desktop)
+3. A detailed dialog with release notes and download options
+
+## Privacy & Security
+
+- Only checks public release information
+- No personal data is transmitted
+- Downloads are handled by the system browser/app store
+- Users control when to update (no forced updates)
