+# **Vanilla HTTP RESTful API**
+
+## **Overview**
+
+  This application is a HTTP RESTful API written in vanilla JavaScript. It utilizes the GET, POST, & DELETE methods to fetch, add, and remove files in a file system.
+
+## **How To Use API**
+  * Clone this repository
+  * Open a terminal and run `npm i` to install all the application dependencies
+
+### **Run your server**
+   `node server.js`
+
+In a new terminal window/tab run your HTTP method commands
+
+### **POST Request**
+  `http POST localhost:[port number]/api/person name='[name]' gender='[gender]'`
+
+### **GET Request**
+  `http GET localhost:[port number]/api/person?id='[id]'`
+
+### **DELETE Request**
+  `http DELETE localhost:[port number]/api/person?id='[id]'`
