### Basic usage

Imagine you have an E-Commerce site, where users can buy items online. When a user places an order, there are several things that needs to happen, E.G place the order, send a order confirmation email to the user, send an order notice to the site admin, create a shipping label etc.

All these processes can be piped together to be executed sequentially.
