+# Task Management System
+
+A simple task management system implementation in Python that allows users to create, update, and manage tasks efficiently.
+
+## Features
+
+- Create tasks with title, description, due date, priority, and status
+- Update task status
+- Remove tasks
+- List all tasks
+- Get specific task details
+
+## Usage
+
+```python
+from task_manager import Task, TaskManager
+
+# Create a task manager
+manager = TaskManager()
+
+# Create a task
+task = Task("Complete Project", "Finish the Python project", "2025-10-30", "high")
+
+# Add task to manager
+task_id = manager.add_task(task)
+
+# Update task status
+manager.update_task_status(task_id, "completed")
+
+# List all tasks
+tasks = manager.list_tasks()
+```
+
+## Running Tests
+
+To run the unit tests:
+
+```bash
+python -m unittest test_task_manager.py
+```
