# "Hello world" example
This example shows a minimal setup for an application using `libweb`. When
executed, it starts a HTTP/1.1 server on port `8080` and returns an example
website reading "Hello from libweb!" when either `/` or `/index.html` are
accessed by clients.
executed, it starts a HTTP/1.1 server on a random port, which is then printed
to the standard output, and returns an example website when either `/` or
`/index.html` are accessed by clients, reading:
```
Hello from libweb!
```
