-//! Module for anonymous pipe
+//!  A cross-platform anonymous pipe.
 //!
-//! ```
-//! #![feature(anonymous_pipe)]
+//! This module provides support for anonymous OS pipes, like [pipe] on Linux or [CreatePipe] on
+//! Windows.
+//!
+//! # Behavior
+//!
+//! A pipe is a synchronous, unidirectional data channel between two or more processes, like an
+//! interprocess [`mpsc`](crate::sync::mpsc) provided by the OS. In particular:
+//!
+//! * A read on a [`PipeReader`] blocks until the pipe is non-empty.
+//! * A write on a [`PipeWriter`] blocks when the pipe is full.
+//! * When all copies of a [`PipeWriter`] are closed, a read on the corresponding [`PipeReader`]
+//!   returns EOF.
+//! * [`PipeReader`] can be shared, but only one process will consume the data in the pipe.
+//!
+//! # Capacity
+//!
+//! Pipe capacity is platform dependent. To quote the Linux [man page]:
+//!
+//! > Different implementations have different limits for the pipe capacity. Applications should
+//! > not rely on a particular capacity: an application should be designed so that a reading process
+//! > consumes data as soon as it is available, so that a writing process does not remain blocked.
 //!
+//! # Examples
+//!
+//! ```no_run
+//! #![feature(anonymous_pipe)]
 //! # #[cfg(miri)] fn main() {}
 //! # #[cfg(not(miri))]
 //! # fn main() -> std::io::Result<()> {
-//! let (reader, writer) = std::pipe::pipe()?;
+//! # use std::process::Command;
+//! # use std::io::{Read, Write};
+//! let (ping_rx, mut ping_tx) = std::pipe::pipe()?;
+//! let (mut pong_rx, pong_tx) = std::pipe::pipe()?;
+//!
+//! // Spawn a process that echoes its input.
+//! let mut echo_server = Command::new("cat").stdin(ping_rx).stdout(pong_tx).spawn()?;
+//!
+//! ping_tx.write_all(b"hello")?;
+//! // Close to unblock echo_server's reader.
+//! drop(ping_tx);
+//!
+//! let mut buf = String::new();
+//! // Block until echo_server's writer is closed.
+//! pong_rx.read_to_string(&mut buf)?;
+//! assert_eq!(&buf, "hello");
+//!
+//! echo_server.wait()?;
 //! # Ok(())
 //! # }
 //! ```
