+## Introduction
+
+---
+Each of us as a customer likes to receive discounts and use promotions.
+However, we mostly use the free shipping option. Adding anything to your cart to keep your shipment free.
+Do you know it?
+
+Sylius shipping subscription plugin offers functionality that allows you to enable free shipping to customers who have purchased a subscription.
+
+## Usage
+
+---
+The plugin works by creating a product that corresponds to a specific subscription.
+The purchase and payment of this item by the customer is equivalent to purchasing a subscription for free shipping.
+
+Then you need to link the subscription to the shipping method and set the minimum order value from which the promotion will apply.
+
+The plugin allows you to specify the price of the subscription and its duration.
+
+### Adding Shipping Subscription as a product
+#### Create a product
+To enable the purchase of a subscription for free shipping you have to create a product. Mark this product as
+a shipping subscription and save.
+<div align="center">
+    <img src="./images/adding_product.png"/>
+</div>
+<br>
+
+#### Create a variant and set the duration
+Once the product is saved, create a variant and set the duration of the subscription (in months).
+<div align="center">
+    <img src="./images/adding_product_variant.png"/>
+</div>
+<br>
+
+#### Create a shipping method
+Now customers can purchase a subscription for free shipping.
+But now you need to create a new shipping method. Set “Is shipping subscription required?” to on.
+Then, type the minimal amount of order from which free shipping will be possible.
+<div align="center">
+    <img src="./images/shipping_method.png"/>
+</div>
+<br>
+
+#### Shipping Subscription list
+Once a user purchases a subscription and payment is confirmed, the subscription is activated.
+You can check the list of subscriptions in the Shipping subscriptions menu.
+<div align="center">
+    <img src="./images/shipping_subscription.png"/>
+</div>
