-> js-library-boilerplate-description.
+Type-check for 'Primitive' types in JavaScript are always something to take care when receiving/sending a payload from/to Server/Client application. If you ever wonder how to do this you can sure use `typeof` and make the check by yourself. Or you can user 🎯`js-is-type`!
+
+The usage is simple and verbose. The tests has full coverage and you can use without a doubt.
+
+## Available Types
+
+- `isArray()`
+- `isBoolean()`
+- `isFunction()`
+- `isObject()` (_Remember: in JS, Arrays are Objects!_)
+- `isString()`
+- `isUndefined()`
 
 ## Installation
 
-js-library-boilerplate is available on npm/yarn:
+`js-is-type` is available on npm/yarn:
 
 ```bash
-$ npm install js-library-boilerplate --save
-$ yarn add js-library-boilerplate
+$ npm install @codevor/js-is-type --save
+$ yarn add @codevor/js-is-type
 ```
 
 ## Usage
 
 ### With ES6/import
 
 ```js
-import { sum } from 'js-library-boilerplate';
+import { isArray } from '@codevor/js-is-type';
 
-sum(2, 2); // => 4
+const names = ['Alice', 'Bob'];
+
+isArray(names); // => true
 ```
 
 ### With require
 
 ```js
-const sum = require('js-library-boilerplate').sum;
+const isArray = require('@codevor/js-is-type').isArray;
+
+const names = ['Alice', 'Bob'];
 
-sum(2, 2); // => 4
+isArray(names); // => true
 ```
