+# Multi-Architecture Offline Installation Guide
+
+## Overview
+The enhanced `install_offline.sh` script automatically detects your system architecture and uses the appropriate libraries.
+
+## Architecture Support
+
+### 64-bit ARM (aarch64) - Raspberry Pi 4/5 with 64-bit OS
+- **Folder used**: `req_libraries/`
+- **Files**: 18 wheel files
+- **Key packages**: 
+  - bcrypt-4.3.0-cp39-abi3-manylinux_2_34_aarch64.whl
+  - pillow-11.3.0-cp311-cp311-manylinux_2_27_aarch64.whl
+  - psutil-7.0.0-cp36-abi3-manylinux_2_17_aarch64.whl
+
+### 32-bit ARM (armv7l) - Raspberry Pi with 32-bit OS
+- **Folder used**: `req_libraries_32bit/`
+- **Files**: 18 wheel files  
+- **Key packages**:
+  - bcrypt-4.3.0-cp311-cp311-linux_armv7l.whl
+  - pillow-11.3.0-cp311-cp311-linux_armv7l.whl
+  - psutil-6.0.0-cp311-abi3-linux_armv7l.whl
+
+## Usage
+
+### Simple Installation (Auto-Detect)
+```bash
+./install_offline.sh
+```
+
+The script will:
+1. Detect your architecture automatically
+2. Choose the correct library folder
+3. Install the appropriate packages
+4. Create a virtual environment
+5. Verify installation
+
+### Manual Architecture Check
+```bash
+uname -m
+```
+- `aarch64` = 64-bit (uses req_libraries/)
+- `armv7l` = 32-bit (uses req_libraries_32bit/)
+
+## Folder Structure
+```
+tkinter_player/
+├── req_libraries/           # 64-bit ARM wheels
+├── req_libraries_32bit/     # 32-bit ARM wheels  
+├── install_offline.sh       # Auto-detecting installer
+└── requirements.txt         # Package list

+
+## Benefits
+- ✅ Single installer for both architectures
+- ✅ Automatic architecture detection
+- ✅ No manual intervention needed
+- ✅ Proper error messages for missing libraries
+- ✅ Complete offline installation support
