| ## Description | |
| The ping example showcases how to create a network of nodes that establish connections, negotiate the ping protocol, and ping each other. | |
| ## Usage | |
| To run the example, follow these steps: | |
| 1. In a first terminal window, run the following command: | |
| ```sh | |
| cargo run | |
| ``` | |
| This command starts a node and prints the `PeerId` and the listening addresses, such as `Listening on "/ip4/0.0.0.0/tcp/24915"`. | |
| 2. In a second terminal window, start a new instance of the example with the following command: | |
| ```sh | |
| cargo run -- /ip4/127.0.0.1/tcp/24915 | |
| ``` | |
| Replace `/ip4/127.0.0.1/tcp/24915` with the listen address of the first node obtained from the first terminal window. | |
| 3. The two nodes will establish a connection, negotiate the ping protocol, and begin pinging each other. | |
| ## Conclusion | |
| The ping example demonstrates the basic usage of **libp2p** to create a simple p2p network and implement a ping protocol. | |
| By running multiple nodes and observing the ping behavior, users can gain insights into how **libp2p** facilitates communication and interaction between peers. | |
