 Before moving into the examples, you should run `npm install` on the top level `js-libp2p` folder, in order to install all the dependencies needed for this example.
 
-This example comes with 3 main files. A `relay.js` file to be used in the first step, a `auto-relay.js` file to be used in the second step and a `other-node.js` file to be used on the third step. All of this scripts will run their own libp2p node, which will interact with the previous ones. This way, you need to have all of them running as you proceed.

 ## 1. Set up a relay node
 
-Aiming to support nodes with connectivity issues, you will need to set up a relay node for the former nodes to bind.
+In the first step of this example, we need to configure and run a relay node in order for our target node to bind to for accepting inbound connections.
 
 The relay node will need to have its relay subsystem enabled, as well as its HOP capability. It can be configured as follows:

-One of the typical use cases for Auto Relay is nodes behind a NAT or browser nodes thanks to their limitations regarding listening for new connections. For running a libp2p node that automatically binds itself to connected HOP relays, you can see the following:
