+
+Thank you for considering contributing to the project. To ensure consistency and maintainability, please follow these style guidelines when submitting code changes.
+
+## Code Style Guidelines
+
+### Coding Standards
+
+- **Indentation**: Use 4 spaces for indentation.
+- **Curly Braces**: Place opening curly braces on the same line as the statement.
+  ```cpp
+  // Example
+  if (condition) {
+      // code
+  }
+  else {
+      // code
+  }
+  ```
+- **Capitalization**: Follow C++ style capitalization.
+  ```cpp
+  // Example
+  int myVariable;
+  
+  void myFunction() {
+      // code
+  }
+  ```
+- **Operators**: Use spaces around operators.
+  ```cpp
+  // Example
+  int sum = a + b;
+
+  if (x == y) {
+      // code
+  }
+  ```
+
+### Code Organization
+
+**Blank Lines**: Include a blank line before and after a code block.
+  ```cpp
+  // Example
+  void functionA() {
+      // code
+  }
+
+  void functionB() {
+      // code
+  }
+  ```
+
+### Encapsulation
+
+**Separate Files or Classes**: Encapsulate significant code changes in separate header files or classes if applicable. This helps maintain a modular and organized codebase, improving readability and reusability.
