+//! # Running the Documentation Server
+//! 
+//! Payphone has a built-in documentation server that serves the project's documentation and
+//! refreshes it on changes. To start the documentation server, run the following command:
+//! 
+//! ```shell
+//! $ cargo run -- docs --open
+//! ```
+//! 
+//! The `--open` flag is optional and will open the documentation in the default browser after
+//! starting the server. You can also use the `--bind` argument to specify the address to bind the
+//! server to, which defaults to `0.0.0.0:3000`.
