-A very easy and lightweight JavaScript library for working with stack data structure.
+
+EZStackJS is a lightweight and easy-to-use JavaScript library designed for working with stack data structures. With EZStackJS, you can effortlessly manage and manipulate stack in your JavaScript applications.
+
+## License
+
+EZStackJS is licensed under the [MIT License](LICENSE).
+
+## Features
+
+- **Simplicity**: EZStackJS provides a straightforward interface for creating, modifying, and traversing stack.
+- **Lightweight**: With minimal dependencies and efficient implementation, EZStackJS offers high performance while keeping your project's footprint small.
+- **Flexibility**: EZStackJS is highly adaptable and can be easily integrated into various JavaScript projects, from small scripts to large-scale applications.
+
+Whether you're a beginner learning about data structures or an experienced developer needing a reliable tool for managing stack, EZStackJS is here to simplify your workflow and empower your projects.
+
+## Installation
+
+To start using EZStackJS in your project, simply install it via npm:
+
+```bash
+npm install ezstackjs
+```
+
+```js
+// Import the Stack class from EZStackJS
+const { Stack } = require('EZStackJS');
+
+// Create a new stack
+const stack = new Stack();
+```
+
+## Method Documentation
+
+EZStackJS provides a variety of methods for creating, modifying, and interacting with stack. Below is an overview of the available methods along with their descriptions and usage examples:
+
+### `.push(item)`
+
+This method inserts the data into the stack
+
+#### Parameters:
+
+- `item`: The item you want to insert to the stack.
+
+### `.peek()`
+
+The method return the last data in the stack (does not remove it).
+
+### Returns:
+- `Any`
+  - Your last item in the stack.
+
+### `.pop()`
+
+This method return the last data and remove it.
+
+#### Returns:
+- `Any`
+  - Your last item in the stack.
+
+### `.size()`
+
+This method return the number of items in the stack.
+
+#### Returns:
+- `Number(int)`
+    - The size of your stack.
+
+### `.isEmpty()`
+
+This method indicates whether the stack is empty or not.
+
+#### Returns:
+
+- `Boolean` 
+  - `true`: Stack is empty.
+  - `false`: Stack is not empty.
+
+### `.toArray()`
+
+This method pours all the data of the stack into an array and returns it.
+
+#### Returns:
+
+- `Array`.
+    - An array of all elements in the stack.
+
+### `.toReverseArray()`
+
+This method puts all elements of the stack in reverse order in the array and returns it.
+
+#### Returns:
+
+- `Array`.
+    - An array of all elements in the reverse array.
+
+Explore the various methods to effectively manage and manipulate stack using EZStackJS in your JavaScript applications.
+
+
+## Advanced Topic: Time Complexity Analysis
+
+Understanding the time complexity of each method can help you optimize your code and make informed decisions when working with large datasets in EZStackJS.
+
+Below is an analysis of the time complexity for each method in the EZStackJS library:
+
+### Time Complexity `.push()`:
+- O(1)
+
+### Time Complexity `.peek()`:
+- O(1)
+
+### Time Complexity `.pop()`:
+- O(1)
+
+### Time Complexity `.size()`:
+- O(1)
+
+### Time Complexity `.isEmpty()`:
+- O(1)
+
+### Time Complexity `.toArray()`:
+- O(n)
+
+### Time Complexity `.toReverseArray()`:
+- O(n)
