This is my final readme file
I added the following code
async function handleTermination() {
    try {
        // Remove the lock to allow future instances
        await lockManager.removeLock();
        
        // Log termination message and exit the process
        logger.info('Application is terminated gracefully.');
        process.exit();
    } catch (error) {
        // Log termination errors and exit the process with an error code
        logger.error('Error during termination:', error);
        process.exit(1);
    }
}

// Handle termination signals to clean up resources before exiting
process.on('exit', handleTermination);
process.on('SIGINT', handleTermination);
process.on('SIGTERM', handleTermination);


I wanted to tell the users that for better robusteness this need to be there

Lock Your Node.js App Into Single-Instance Mode with Ease!
</p>

Node Locksmith is an elegant and straightforward Node.js module that ensures your application runs as a single instance, preventing multiple executions that could lead to data corruption or unexpected behavior. Imagine a world where starting your app twice is impossible – that's the peace of mind Node Locksmith offers!

Whether you're managing batch jobs, cron tasks, or any other Node.js scripts, Node Locksmith keeps them unique so your system stays safe and predictable.

### 🌟 Features

- Effortless Integration: Just a few lines of code to make your app single-instance.
- Automatic Lock Management: Creates and releases locks without a fuss.
- Customizable Behaviors: Decide how your app responds to duplicate runs.
- Cross-Platform Support: Works on both Windows and Unix-like systems.
- Safe & Secure: Ensures only one instance manages crucial tasks at a time.

### 💻 Installation

Getting started with Node Locksmith is a snap! Run this command:

npm install node-locksmith

### 🚀 Quick Start

Here's how simple it is to use Node Locksmith:
```
// Import the LockManager class
const LockManager = require('node-locksmith');

// Create a new instance with optional custom settings
const lockManager = new LockManager({
lockFileName: 'myApp.lock' // Customize your lock file name
});

async function main() {
// Check and create a lock before running your app logic
await lockManager.checkLock();
await lockManager.createLock();

    // Your app logic goes here

    // When all done, cleanup by removing the lock
    await lockManager.removeLock();

}

// Start your app with LockManager in control
main();

async function handleTermination() {
    try {
        // Remove the lock to allow future instances
        await lockManager.removeLock();
        
        // Log termination message and exit the process
        logger.info('Application is terminated gracefully.');
        process.exit();
    } catch (error) {
        // Log termination errors and exit the process with an error code
        logger.error('Error during termination:', error);
        process.exit(1);
    }
}

// Handle termination signals to clean up resources before exiting
process.on('exit', handleTermination);
process.on('SIGINT', handleTermination);
process.on('SIGTERM', handleTermination);

```
And voilà – you're now running with a robust single-instance lock!
