+# Food Lion - Load All To Card
+
+## Introduction
+
+This is a Chrome extension that adds a "Load All To Card" button to the Food
+Lion [MVP Coupons Center](https://www.foodlion.com/coupons/). The Javascript
+action on this button will click on all the coupons in one shot, adding all of
+them to the card.
+
+## Installation
+
+git clone this repository to your local disk or download the zip file and extract.
+
+Go to the Chrome extensions page (chrome://extensions). You'll need to enable
+developer mode in order to load an unpacked extension.
+
+Click on "Load unpacked extension" and navigate to the folder in which you
+cloned or extracted the source files. Select this folder to load the extension.
+
+## Usage
+
+Once you've installed and enabled this extension, go to the Food Lion MVP
+Coupons Center and find the "Load All To Card" button on the top left corner.
+Click on it and it will load all the coupons to your card.
+
+Note: this button works only on coupons that are currently visible on the
+page. If you have a lot of coupons to load, you will need to scroll down to
+make the Food Lion website display more coupons.
