+## Dual Module Support
+
+This package supports both:
+
+- ES Modules: `import argv2object from 'argv2object'`
+- CommonJS: `const argv2object = require('argv2object')`
+
+The architecture uses separate entry points while sharing the same implementation.
+
+## System Requirements
+
+- **Node.js 14+** (Recommended for full support)
+- **Node.js 12.x** (Experimental support)
+- **Versiones anteriores**: Use version 1.x of this package
+
 ## Examples
 
 ### Simple key-value pairs
 
 ```sh
 # Command line input:
-node script.js task=some-task name=John level=admin
+node script.js task=some-task age=30 name=John level=admin
 
 ```
 
 ```js
 const args = argv2Object();
 console.log(args);
-// Output: { name: 'John', age: '30', level: 'admin' }
+// Output: { name: 'John', age: 30, level: 'admin' }
 ```
 
 ### Unix-style command-line options
 
 ```sh
 # Command line input:
-node --watch script.js -h --name=John --is-admin
+node --watch script.js -h --help --name=John --is-admin
 
 ```
 
 ```js
 const args = argv2Object(true);
 console.log(args);
-// Output: { h: true, name: 'John', is_admin: true }
+// Output: { h: true, help: true, name: 'John', is_admin: true }
 ```
