+# HMAC File Server Installer Enhancements - COMPLETED
+
+## Summary
+All requested enhancements have been successfully implemented and validated in the HMAC File Server installer script.
+
+## ✅ Enhancement 1: Selectable Configuration Directory
+**Status: COMPLETED**
+- Modified `get_user_input()` function to prompt users for custom configuration directory
+- Changed from hardcoded `DEFAULT_CONFIG_DIR` to user-selectable `CONFIG_DIR` variable
+- Updated all references throughout the script to use the `CONFIG_DIR` variable
+- Maintains backward compatibility with default `/etc/hmac-file-server` if user presses Enter
+
+## ✅ Enhancement 2: Removed Duplicate Output on Finalization
+**Status: COMPLETED**
+- Eliminated redundant installation completion messages
+- Consolidated completion information into single `print_completion_info()` function
+- Function is called only once in the native installation workflow
+- Docker deployment has its own streamlined completion message
+- No more duplicate service information or endpoint details
+
+## ✅ Enhancement 3: Removed All Emoticons and Unicode Symbols
+**Status: COMPLETED**
+- Systematically removed all Unicode characters including:
+  - ✓, ✅, ❌, ⚠️ (checkmarks and warning symbols)
+  - 🚀, 🌐, 📁, ⚡, 🔧, 📚 (various emoji)
+  - • (bullet points)
+  - █ (block characters)
+  - ──── (Unicode dashes)
+- Replaced with standard ASCII equivalents (-, +, *, etc.)
+- Script now uses only standard ASCII characters for universal compatibility
+
+## ✅ Enhancement 4: Docker Deployment Option
+**Status: COMPLETED**
+- Added comprehensive Docker deployment workflow as alternative to native installation
+- Created installation type selection menu (Native vs Docker)
+- Implemented Docker-specific functions:
+  - `create_docker_deployment()` - Sets up complete Docker environment
+  - `generate_docker_config()` - Creates container-optimized configuration
+- Features included:
+  - Multi-service docker-compose.yml with Redis and ClamAV
+  - Multi-stage Dockerfile for optimized container builds
+  - Automated start/stop scripts for easy management
+  - Container-specific directory structure and volume mappings
+  - Proper networking between services
+- Updated help documentation to reflect Docker option
+
+## 🧪 Validation Results
+- **Syntax Check**: ✅ PASSED - No bash syntax errors
+- **Help Function**: ✅ PASSED - Docker deployment mentioned
+- **Unicode Removal**: ✅ PASSED - No Unicode symbols found
+- **CONFIG_DIR Usage**: ✅ PASSED - Consistently used throughout (Docker container paths excluded)
+- **Docker Functions**: ✅ PASSED - All Docker functions present and working
+- **Duplicate Prevention**: ✅ PASSED - Completion info displayed only once
+- **Script Structure**: ✅ PASSED - All key functions present and functional
+
+## 📁 Files Modified
+- **Main Script**: `/home/renz/source/hmac-file-server/installer.sh` (extensively enhanced)
+- **Documentation**: Updated `README.MD`, `INSTALL.MD`, `WIKI.MD`, `CHANGELOG.MD`
+- **Test Scripts**: Created validation scripts to ensure functionality
+
+## 🔧 Technical Implementation Details
+
+### Configuration Directory Selection
+```bash
+# User can now customize config directory
+read -p "Configuration directory [$DEFAULT_CONFIG_DIR]: " CONFIG_DIR
+CONFIG_DIR=${CONFIG_DIR:-$DEFAULT_CONFIG_DIR}
+```
+
+### Docker Deployment Structure
+- Isolated directory structure with proper volume mappings
+- Redis and ClamAV services properly networked
+- Container-optimized paths (/var/lib, /var/log, /etc)
+- Both deployment types maintain same configuration options
+
+### Code Quality
+- Maintains all existing functionality
+- Backward compatible with previous usage patterns
+- Follows bash best practices
+- Comprehensive error handling preserved
+
+## 🎯 Outcome
+The HMAC File Server installer script now provides:
+1. **Flexible Configuration**: Users can select custom configuration directories
+2. **Clean Output**: No duplicate information during installation
+3. **Universal Compatibility**: Works with all terminal types (no Unicode dependencies)
+4. **Modern Deployment Options**: Choice between traditional systemd service or containerized Docker deployment
+
+The installer is production-ready and significantly enhanced while maintaining full backward compatibility.
+
+## 📖 Documentation Updates
+All documentation files have been updated to reflect the new capabilities:
+- **README.MD**: Updated installation section with deployment options
+- **INSTALL.MD**: Added comprehensive Docker deployment instructions
+- **WIKI.MD**: Enhanced Docker section with automated deployment info
+- **CHANGELOG.MD**: Documented all enhancements in version 3.2
+
+The project documentation now accurately reflects both the traditional installation method and the new automated Docker deployment option, providing users with clear guidance for their preferred deployment strategy.

+The easiest way to deploy with Docker is using the automated installer:
+
+```bash
+git clone https://github.com/PlusOne/hmac-file-server.git
+cd hmac-file-server
+sudo ./installer.sh

+- Generate an optimized multi-stage Dockerfile
+- Set up proper networking between services
+- Create start/stop scripts (`start.sh`, `stop.sh`)
+- Configure container-optimized configuration
+- Provide an isolated deployment directory structure
