+# Repo-to-Knowledge Mapper
+A lightweight Python static analysis tool that generates a structured Markdown map of your project's architecture.
+
+## Purpose
+Onboarding to a new codebase is hard. This script scans a directory and extracts a high-level overview of classes and public methods using Python's Abstract Syntax Tree (AST), helping developers understand "what lives where" without manual auditing.
+
+## Installation
+1. Clone the repository.
+2. Install testing dependencies:
+
+   ```bash
+   pip install -r requirements.txt
