 ## Installation
 
+First, save the [`marko`](https://www.npmjs.com/package/marko) and [`redux`](https://www.npmjs.com/package/redux) packages to your project’s dependencies:
+
 ```bash
-npm install redux --save
-npm install marko --save
+npm i marko redux
 ```
 
 ## Usage

-to a Redux store using the `store.subscribe()` method and the Marko `forceUpdate()`
