+## 📖 About The Project
+
+**Python Code Validator** is an engine designed for educational platforms and automated testing systems. It solves a key
+problem: **how to verify that a student's code meets specific structural and stylistic requirements *before* running
+resource-intensive dynamic tests.**
+
+Instead of writing complex Python scripts for each new validation rule, you can define them declaratively in a simple,
+powerful **JSON format**. This allows teachers and curriculum developers to easily create and adapt validation scenarios
+without deep programming knowledge. The framework analyzes the code's Abstract Syntax Tree (AST), providing a deep and
+reliable way to enforce best practices.
+
+## 📈 The Power of Combinatorics
+
+The framework's power lies in its combinatorial architecture. It is built on a small set of primitive "bricks": *
+*Selectors** (`S`) that define *what* to find in the code, and **Constraints** (`C`) that define *what condition* to
+check.
+
+The number of unique validation rules (`R`) is not a sum, but a product of these components. A single rule can be
+represented as:
+$$ R_{\text{single}} = S \times C $$
+With approximately 10 types of selectors and 10 types of constraints, this already provides ~100 unique checks. However,
+the true flexibility comes from logical composition, allowing for a near-infinite number of validation scenarios:
+$$ R_{\text{total}} \approx S \times \sum_{k=1}^{|C|} \binom{|C|}{k} = S \times (2^{|C|} - 1) $$
+This design provides **thousands of potential validation scenarios** out-of-the-box, offering extreme flexibility with
+minimal complexity.
+
+## ✨ Key Features
+
+- **Declarative JSON Rules**: Define validation logic in a human-readable format.
+- **Powerful Static Analysis**:
+    - ✅ Check syntax and PEP8 compliance (`flake8`).
+    - ✅ Enforce or forbid specific `import` statements.
+    - ✅ Verify class structure, inheritance, and function signatures.
+    - ✅ Forbid "magic numbers" or specific function calls like `eval`.
+- **Precise Scoping**: Apply rules globally, or narrowly to a specific function, class, or method.
+- **Extensible Architecture**: Easily add new, custom checks by creating new Selector or Constraint components.
+
+## 🚀 Getting Started
+
+### Installation
+
+**1. For Users (from PyPI):**
+
+Install the package with one command. This will make the `validate-code` command-line tool available.
+
+```bash
+pip install python-code-validator
+```
+
+**2. For Users (from source):**
+
+If you want to install directly from the repository:
+
+```bash
+git clone https://github.com/Qu1nel/PythonCodeValidator.git
+cd PythonCodeValidator
+pip install .
+```
+
+**3. For Developers:**
+
+To set up a full development environment, see the [Contributing Guidelines](./CONTRIBUTING.md).
+
+## ⚡ Quick Usage Example
+
+The validator is a command-line tool named `validate-code`.
+
+### Example 1: Simple Check
+
+Let's check if a required function exists.
+
+**`solution_simple.py`:**
+
+```python
+# This file is missing the 'solve' function
+def main():
+    print("Hello")
+```
+
+**`rules_simple.json`:**
+
+```json
+{
+  "validation_rules": [
+    {
+      "rule_id": 1,
+      "message": "Required function 'solve' is missing.",
+      "check": {
+        "selector": {
+          "type": "function_def",
+          "name": "solve"
+        },
+        "constraint": {
+          "type": "is_required"
+        }
+      }
+    }
+  ]
+}
+```
+
+**Running the validator:**
+
+```bash
+$ validate-code solution_simple.py rules_simple.json
+Starting validation for: solution_simple.py
+Required function 'solve' is missing.
+Validation failed.
+```
+
+### Example 2: Advanced Check
+
+Let's enforce a complex rule: "In our game class, the `update` method must not contain any `print` statements."
+
+**`game.py`:**
+
+```python
+import arcade
+
+
+class MyGame(arcade.Window):
+    def update(self, delta_time):
+        print("Debugging player position...")  # Forbidden call
+        self.player.x += 1
+```
+
+**`rules_advanced.json`:**
+
+```json
+{
+  "validation_rules": [
+    {
+      "rule_id": 101,
+      "message": "Do not use 'print' inside the 'update' method.",
+      "check": {
+        "selector": {
+          "type": "function_call",
+          "name": "print",
+          "in_scope": {
+            "class": "MyGame",
+            "method": "update"
+          }
+        },
+        "constraint": {
+          "type": "is_forbidden"
+        }
+      }
+    }
+  ]
+}
+```
+
+**Running the validator:**
+
+```bash
+$ validate-code game.py rules_advanced.json
+Starting validation for: game.py
+Do not use 'print' inside the 'update' method.
+Validation failed.
+```
