Installation and Setup

Prerequisites

Node.js (v14 or higher)
MongoDB (local or cloud instance)

Steps to Set Up

Clone the repository:

git clone https://github.com/your-repo/task-management-api.git
cd task-management-api

Install dependencies:
```
npm install
```

Set up environment variables: Create a .env file in the project root and add the following:

PORT=5000
MONGO_URI=mongodb+srv://<username>:<password>@cluster0.mongodb.net/taskdb
JWT_SECRET=your_jwt_secret_key

Start the MongoDB server (if running locally) and seed your database as needed.
Start the API:
```
npm start
```
The API will be running on http://localhost:5000.
