+# Simple KNN & Decision Tree Classifiers
+
+This project demonstrates the implementation of the k-Nearest Neighbors (KNN) and Decision Tree algorithms from scratch in Python using a sample dataset of 2D points with binary class labels.
+
+## Features
+
+- **KNN Classifier:** Find the class of a test point using the majority class of the k nearest neighbors.
+- **Decision Tree Classifier:** Build a decision tree classifier based on information gain and classify new data points.
+- **Sample Dataset:** 50 manually defined (x, y, label) tuples.
+- **Multiple Test Points:** Easily classify a list of new data points.
+
+## Requirements
+
+- Python 3.x
+- (Optional) Libraries like numpy, pandas, scikit-learn, matplotlib for future enhancements.
+
+See [`requirements.txt`](requirements.txt) for details.
+
+## Usage
+
+1. Clone this repository:
+
+    ```
+    git clone https://github.com/yourusername/simple-knn-decisiontree.git
+    cd simple-knn-decisiontree
+    ```
+
+2. Run the classifiers:
+
+    ```
+    python knn_decision_tree.py
+    ```
+
+    You can modify the `test_points` list to classify different points.
+
+## Files
+
+- `knn_decision_tree.py`: Contains the implementations for KNN and Decision Tree, plus the sample dataset.
+- `requirements.txt`: (Optional) Lists external libraries for extended functionality.
+- `README.md`: Project introduction and usage.
+
+## Extending the Project
+
+- Integrate sklearn for quick benchmarking.
+- Add plotting with matplotlib to visualize the dataset and decision boundaries.
+- Use pandas for reading larger datasets from CSV files.
