             ## 📋 Usage Instructions
             
             ### 1. Write Your Code
             - Enter your Python code in the code editor
             - Add Python package requirements in the requirements tab
-            - For Windows .exe, consider adding `input('Press Enter to exit...')` to prevent console closing
-            
-            ### 2. Choose Target Platform
-            - **Linux (.bin)**: Native Linux executable (fastest compilation)
-            - **Linux (.sh)**: Shell script format
-            - **Windows (.exe)**: Cross-compiled using comprehensive MinGW-w64 setup (guaranteed 64-bit)
-            
-            ### 3. Compile
-            - Click "Compile with Nuitka"
-            - Watch logs for comprehensive environment setup
-            - Monitor architecture verification in real-time
-            - Download the verified 64-bit binary
-            
-            ### 4. Verify Your Binary
-            The app automatically verifies the output:
-            - Checks for PE32+ signature (64-bit Windows)
-            - Displays architecture in logs
-            - Warns if unexpected architecture is detected
-            - Confirms successful 64-bit compilation
-            
-            ## 🔧 Environment Variables Set
-            
-            **For guaranteed 64-bit compilation, the app sets:**
-            
-            ```bash
-            # Compilers and tools
-            CC=x86_64-w64-mingw32-gcc
-            CXX=x86_64-w64-mingw32-g++
-            AR=x86_64-w64-mingw32-ar
-            NM=x86_64-w64-mingw32-nm
-            STRIP=x86_64-w64-mingw32-strip
-            RANLIB=x86_64-w64-mingw32-ranlib
-            OBJCOPY=x86_64-w64-mingw32-objcopy
-            OBJDUMP=x86_64-w64-mingw32-objdump
-            
-            # Cross-compilation control
-            CROSS_COMPILE=x86_64-w64-mingw32-
-            TARGET=x86_64-w64-mingw32
-            TARGET_ARCH=x86_64
-            
-            # Compilation flags
-            CFLAGS=-m64
-            CXXFLAGS=-m64
-            LDFLAGS=-m64
+            - For Windows .exe, consider adding `input('Press Enter to exit...')`
+            
+            ### 2. Compilation Process
+            - **Linux (.bin)**: Native compilation with network handling
+            - **Windows (.exe)**: 64-bit cross-compilation + network handling
+            - The system automatically adds error handling for network issues
+            
+            ### 3. Network Considerations
+            If your code uses online services (like Hugging Face):
+            - **Development**: Works normally with internet access
+            - **Compiled binary**: Includes enhanced error handling
+            - **Error messages**: Provide clear guidance on failures
+            
+            ## 🌐 Network Error Handling
+            
+            **What's Enhanced:**
+            ```python
+            # Automatic wrapping of network operations
+            # Enhanced urllib error handling
+            # DNS resolution error detection
+            # Exit code 6 for network issues
+            # Helpful error messages
             ```
             
-            ## ⚠️ Troubleshooting
+            **When Network Errors Occur:**
+            1. **DNS Resolution Fails**: Clear message about host resolution
+            2. **Exit Code 6**: Consistent with original issue
+            3. **Error Guidance**: Suggestions for offline operation
+            4. **Debugging Info**: Shows exact error cause
+            
+            ## 🔧 Solutions for Common Issues
+            
+            **If you get "Could not resolve host: huggingface.co":**
+            
+            1. **For Development:**
+               - Ensure internet connectivity
+               - Check firewall settings
+               - Verify DNS configuration
+            
+            2. **For Compiled Binaries:**
+               - Pre-download models before compilation
+               - Use offline mode if available
+               - Cache required data locally
+               - Configure libraries for offline use
+            
+            **Example for Offline Hugging Face:**
+            ```python
+            # Pre-download and use local models
+            from transformers import AutoModel, AutoTokenizer
+            
+            # Download once during development
+            model = AutoModel.from_pretrained("model-name", cache_dir="./models")
+            tokenizer = AutoTokenizer.from_pretrained("model-name", cache_dir="./models")
+            
+            # Use offline mode in compiled binary
+            model = AutoModel.from_pretrained("./models/model-name", local_files_only=True)
+            ```
             
-            **If you still get a 32-bit executable:**
+            ## 📊 Error Code Reference
             
-            1. **Check the logs** - The app shows all environment variables set
-            2. **Verify MinGW-w64** - Ensure x86_64-w64-mingw32-gcc is available
-            3. **Package compatibility** - Some Python packages may override settings
-            4. **Try different modes** - Test with different compilation modes
+            | Exit Code | Meaning | Solution |
+            |-----------|---------|----------|
+            | 0 | Success | Normal operation |
+            | 6 | Network Error | DNS resolution failed |
+            | Other | Various Errors | Check error message |
             
-            **Common issues:**
-            - Some packages force 32-bit compilation
-            - Virtual environments may have conflicting settings
-            - Old MinGW installations may interfere
+            ## ⚠️ Best Practices
             
-            ## 📊 Verification Process
+            **For Network-Dependent Applications:**
+            1. Always handle network errors gracefully
+            2. Provide fallback mechanisms
+            3. Cache data when possible
+            4. Use offline modes where available
+            5. Display helpful error messages to users
             
-            | Step | Check | Expected Result |
-            |------|-------|----------------|
-            | 1. Environment | 15+ variables set | All cross-compilation variables |
-            | 2. Compilation | --mingw64 flag | Uses MinGW-w64 toolchain |
-            | 3. Output check | file command | PE32+ (64-bit Windows) |
-            | 4. Verification | Log confirmation | "64-bit" in output |
+            **For Windows .exe Distribution:**
+            1. Test compiled binary on clean Windows system
+            2. Verify network error handling works
+            3. Include instructions for users about network requirements
+            4. Consider bundling required data with executable
