+
+## Installation:
+Install this tool from **npm** globally:
+```bash
+$ npm install aes256-cli -g
+```
+
+## Usage:
+This is a CLI tool to encrypt and decrypt files and texts, it uses the [aes256](https://github.com/JamesMGreene/node-aes256) Node.js module for that.  
+The `aes256` module provides a simple way to encrypt/decrypt data, it's based on the built-in `crypto` Node.js module, it uses the aes-256-ctr algorithm.  
+To get started, run the following command then follow the instructions:
+
+```shell
+$ aes256-cli
+```
+You can also run it directly without installation, with **npx**:
+```shell
+$ npx aes256-cli
+```
+
+## Notes:
+Thank you for using AES256 CLI ❤. If you liked it don't forget to leave a star ⭐!
