+
+### Key Features Implemented
+
+#### 1. JSON Configuration Parser
+- **Models**: Created strongly-typed C# classes for configuration
+  - `AppConfiguration`: Root configuration object
+  - `Application`: Individual application definition
+  - `InstallOptions`: Installation preferences
+  - `ConfigurationSettings`: Global settings
+
+#### 2. Configuration Validation
+- Validates required fields (id, name, source)
+- Checks for empty application lists
+- Validates configuration settings
+- Provides detailed error messages with field-level feedback
+
+#### 3. Logging System
+- Color-coded console output:
+  - White: Information
+  - Yellow: Warnings
+  - Red: Errors
+  - Gray: Debug
+- Configurable log levels: Debug, Information, Warning, Error
+- Timestamped log entries
+- Clean, professional output format
+
+#### 4. WinGet Configuration Builder
+- Generates valid WinGet DSC YAML from JSON
+- Supports OS version assertions
+- Developer Mode enablement option
+- Proper YAML formatting with schema reference
+- Sanitizes IDs for YAML compatibility
+
+#### 5. WinGet Integration
+- Programmatic execution of WinGet commands
+- Asynchronous process handling
+- Real-time output streaming
+- Error capture and reporting
+- Exit code handling
+- WinGet availability checking
+
+#### 6. Error Handling
+- Comprehensive try-catch blocks
+- JSON parsing error handling
+- File I/O error handling
+- Process execution error handling
+- User-friendly error messages
+- Non-zero exit codes for failures
+
+### Sample JSON Configuration
+```json
+{
+  "applications": [
+    {
+      "id": "Microsoft.VisualStudioCode",
+      "name": "Visual Studio Code",
+      "source": "winget",
+      "installOptions": {
+        "silent": true,
+        "acceptPackageAgreements": true
+      },
+      "description": "Install Visual Studio Code"
+    }
+  ],
+  "configuration": {
+    "minOsVersion": "10.0.22631",
+    "enableDeveloperMode": true,
+    "logLevel": "Information"
+  }
+}
+```
+
+### Generated WinGet YAML
+The application generates standard WinGet DSC YAML files compatible with:
+- WinGet DSC schema 0.2
+- Microsoft.Windows.Developer resources
+- Microsoft.WinGet.DSC resources
+
+## Testing Results
+
+### Validation Testing
+✅ Successfully detects missing required fields
+✅ Properly validates empty application lists
+✅ Correctly identifies configuration errors
+✅ Provides clear error messages
+
+### YAML Generation Testing
+✅ Generates valid WinGet DSC YAML
+✅ Includes all required sections (assertions, resources)
+✅ Properly formats package entries
+✅ Adds schema references
+
+### Application Flow Testing
+✅ Help command works correctly
+✅ Configuration file loading successful
+✅ JSON parsing works properly
+✅ Graceful handling when WinGet unavailable
+✅ Proper exit codes (0 for success, 1 for errors)
+
+## Security Scan Results
+- **CodeQL Analysis**: ✅ No vulnerabilities detected
+- **Code Review**: ✅ No issues found
+
+## Documentation

+
+## Usage
+
+### Basic Usage
+
+Run the application with the default configuration file (`apps-config.json`):
+
+```bash
+dotnet run
+```
+
+Or if you've built the executable:
+
+```bash
+WinGetConfigApplier.exe
+```
+
+### Custom Configuration
+
+Specify a custom configuration file and output path:
+
+```bash
+dotnet run -- myconfig.json output.yaml
+```
+
+Or:
+
+```bash
+WinGetConfigApplier.exe myconfig.json output.yaml
+```
+
+### Command Line Arguments
+
+```
+WinGetConfigApplier [config-file] [output-file]
+
+Arguments:
+  config-file    Path to JSON configuration file (default: apps-config.json)
+  output-file    Path to output YAML file (default: generated-winget-config.yaml)
+
+Options:
+  --help, -h     Display help message
+```
+
+## Configuration File Format
+
+The JSON configuration file should follow this structure:
+
+```json
+{
+  "applications": [
+    {
+      "id": "Microsoft.VisualStudioCode",
+      "name": "Visual Studio Code",
+      "source": "winget",
+      "installOptions": {
+        "silent": true,
+        "acceptPackageAgreements": true
+      },
+      "description": "Install Visual Studio Code"
+    }
+  ],
+  "configuration": {
+    "minOsVersion": "10.0.22631",
+    "enableDeveloperMode": true,
+    "logLevel": "Information"
+  }
+}
+```
+
+### Configuration Properties
+
+#### Application Object
+
+- `id` (required): The WinGet package identifier (e.g., `Microsoft.VisualStudioCode`)
+- `name` (required): Display name for the application
+- `source` (required): Package source (typically `winget` or `msstore`)
+- `installOptions`: Installation options
+  - `silent`: Enable silent installation (default: `true`)
+  - `acceptPackageAgreements`: Automatically accept package agreements (default: `true`)
+- `description`: Description shown during installation
+
+#### Configuration Settings
+
+- `minOsVersion`: Minimum Windows OS version required (default: `10.0.22631`)
+- `enableDeveloperMode`: Enable Windows Developer Mode (default: `false`)
+- `logLevel`: Logging verbosity - `Debug`, `Information`, `Warning`, or `Error` (default: `Information`)
+
+## Building the Application
+
+### Debug Build
+
+```bash
+dotnet build
+```
+
+### Release Build
+
+```bash
+dotnet build -c Release
+```
+
+The compiled executable will be in:
+- Debug: `bin/Debug/net9.0/`
+- Release: `bin/Release/net9.0/`
+
+### Publishing
+
+To create a self-contained executable:
+
+```bash
+dotnet publish -c Release -r win-x64 --self-contained
+```
+
+The published application will be in `bin/Release/net9.0/win-x64/publish/`
+
+## Logging
+
+The application provides color-coded console logging:
+
+- **White**: Informational messages
+- **Yellow**: Warnings
+- **Red**: Errors
+- **Gray**: Debug messages (when log level is set to Debug)
+
+Each log entry includes a timestamp in the format: `[LEVEL] yyyy-MM-dd HH:mm:ss - message`
+
+## Error Handling
+
+The application includes comprehensive error handling:
+
+1. **Configuration Validation**: Validates JSON structure and required fields before processing
+2. **WinGet Availability Check**: Verifies WinGet is installed before attempting installations
+3. **Process Error Handling**: Captures and logs WinGet output and errors
+4. **Exit Codes**:
+   - `0`: Success
+   - `1`: Error (configuration invalid, WinGet not available, installation failed, etc.)
+
+## Example Workflow
+
+1. **Create or modify** `apps-config.json` with desired applications
+2. **Run the application**: `dotnet run`
+3. **Review the summary** of applications to be installed
+4. **Confirm** when prompted (y/N)
+5. **Monitor progress** through console logs
+6. **Check results** - successful installations or error messages
+
+## Sample Output
+
+```
+=== WinGet Configuration Applier ===

+
+## Troubleshooting
+
+### WinGet Not Found
+
+If you see "WinGet is not available on this system":
+1. Install WinGet from https://aka.ms/getwinget
+2. Restart your terminal/command prompt
+3. Run `winget --version` to verify installation
+
+### Configuration Validation Errors
+
+The validator will provide specific error messages for:
+- Missing required fields (id, name, source)
+- Empty application lists
+- Invalid configuration structure
+
+### Installation Failures
+
+If an installation fails:
+- Check the console output for specific error messages
+- Review the generated YAML file for correctness
+- Verify the package ID exists in WinGet: `winget search <package-id>`
+- Check WinGet logs for detailed error information
