+# ABAP Code Scanner Framework
+
+## Overview
+
+The ABAP Code Scanner Framework is a powerful tool designed to analyze ABAP (Advanced Business Application Programming) code for potential security vulnerabilities, code quality issues, and best practice violations. This framework provides a flexible and extensible way to scan ABAP code and generate comprehensive reports on various aspects of code security and quality.
+
+## Features
+
+- Multiple security checks including:
+  - Cross-Site Scripting (XSS) vulnerabilities
+  - Directory Traversal vulnerabilities
+  - Hardcoded credentials
+  - Weak cryptographic algorithms
+  - And many more...
+- Customizable and extensible architecture
+- Command-line interface for easy integration into CI/CD pipelines
+- Detailed reporting in XLSX format
+- Configurable scan settings
+
+## Prerequisites
+
+- Python 3.9 or higher
+- pip (Python package installer)
+
+## Installation
+
+1. Clone the repository:
+   ```
+   git clone https://github.com/yourusername/AbapCodeScannerFramework.git
+   cd AbapCodeScannerFramework
+   ```
+
+2. Install the required dependencies:
+   ```
+   pip install -r requirements.txt
+   ```
+
+## Usage
+
+To run the ABAP Code Scanner:
+
+```
+python main.py path/to/abap/code
+```
+
+Optional arguments:
+- `-c`, `--config`: Path to the configuration file (default: config.yml)
+
+## Configuration
+
+The scanner can be configured using a YAML file. By default, it looks for `config.yml` in the project root. You can specify a different configuration file using the `-c` or `--config` option.
+
+Example configuration:
+
+```yaml
+checks:
+  - CheckCrossSiteScripting
+  - CheckSQLInjection
+  - CheckDirectoryTraversal
+
+file_extensions:
+  - .abap
+  - .txt
+
+exclude_patterns:
+  - "**/test/**"
+```
+
+## Adding New Checks
+
+To add a new security check:
+
+1. Create a new Python file in the `checks` directory.
+2. Define a class that inherits from a base check class.
+3. Implement the required methods, including the main `run` method.
+4. Add the new check to the configuration file.
+
+## Running Tests
+
+To run the test suite:
+
+On Windows:
+```
+run_tests.bat
+```
+
+On Unix-like systems:
+```
+./run_tests.sh
+```
+
+## Contributing
+
+Contributions to the ABAP Code Scanner Framework are welcome! Please feel free to submit pull requests, create issues or spread the word.

+## Acknowledgments
+
+- Thanks to all contributors who have helped to improve this framework.
+- Special thanks to the ABAP community for their invaluable resources and documentation.
