 # Data Structures and Algorithms in JavaScript
 
+[![Build Status](https://travis-ci.com/amejiarosario/dsa.js.svg?branch=master)](https://travis-ci.com/amejiarosario/dsa.js)
+[![npm version](https://badge.fury.io/js/dsa.js.svg)](https://badge.fury.io/js/dsa.js)
+
 This repository covers the implementation of the classical algorithms and data structures in JavaScript.
 
-<!-- This goes along with [these posts series](https://adrianmejia.com/tags/tutorial-algorithms/) that explain each implementation in details and also this [book](https://gum.co/dsajs) that explain these topics and some with more examples and illustrations. -->
+## Usage
+
+You can clone the repo or install the code from NPM:
+
+```sh
+npm install dsa.js
+```
+
+and then you can import it into your programs or CLI
+
+```js
+const { LinkedList, Queue, Stack } = require('dsa.js');
+```
+
+For a full list of all the exposed data structures and algorithms [see](https://github.com/amejiarosario/dsa.js/blob/master/src/index.js).
 
 ## Book
 
-You can check out the book that goes deeper into each topic and provide addtional illustrations and explanations.
