+**🔧 Dynamic Runtime Configuration**
+DexDumper features an advanced runtime configuration system that allows you to customize behavior without recompiling:
+
+- Automatically detects and pairs configuration files with library names.
+- If no config exists, DexDumper creates a detailed, commented configuration file.
+
+*How it works:* The library automatically extracts its own filename (e.g., `libdexdumper.so` → `dexdumper.conf`) and searches for matching configuration files. This ensures that even when you rename the library for stealth, the configuration system remains functional.

+### Runtime Configuration ([LIBRARY_NAME].conf)
+
+DexDumper automatically creates and reads configuration files at runtime. No recompilation needed!
+
+**Configuration File Locations:**
+- `/data/data/[PACKAGE]/files/[LIBRARY_NAME].conf`
+- `/data/user/0/[PACKAGE]/files/[LIBRARY_NAME].conf` 
+- `/storage/emulated/0/Android/data/[PACKAGE]/files/[LIBRARY_NAME].conf`
+
+**First Run Behavior:**
+- Automatically generates a detailed configuration file with explanations
+- Uses compile-time defaults until you customize the file  
+- File includes comprehensive comments for every setting
+
+**To customize:** Edit the generated `.conf` file, save, and restart the app. The library will use your new settings immediately.

 ## 📊 Performance Considerations
 
 - **Memory Usage**: Minimal impact (typically < 10MB)
