-//! # Rust email client
+//! Lettre is a mailer written in Rust. It provides a simple email builder and several transports.
 //!
-//! This client should tend to follow [RFC
+//! ## Architecture
+//!
+//! This mailer is divided into:
+//!
+//! * An `email` part: builds the email message
+//! * A `transport` part: contains the available transports for your emails. To be sendable, the emails have to implement `SendableEmail`.
+//!
+//! ## Stub transport
+//!
+//! The stub transport only logs message envelope and drops the content. It can be useful for testing purposes.
+//!
+//! ```rust
+//! use lettre::transport::stub::StubEmailTransport;
+//! use lettre::transport::EmailTransport;
+//! use lettre::email::EmailBuilder;
+//!
+//! let mut sender = StubEmailTransport;
+//! let email = EmailBuilder::new()
+//!                     .to("root@localhost")
+//!                     .from("user@localhost")
+//!                     .body("Hello World!")
+//!                     .subject("Hello")
+//!                     .build()
+//!                     .unwrap();
+//! let result = sender.send(email);
+//! assert!(result.is_ok());
+//! ```
+//!
+//! Will log the line:
+//!
+//! ```text
+//! b7c211bc-9811-45ce-8cd9-68eab575d695: from=<user@localhost> to=<root@localhost>
+//! ```
+//!
+//! ## File transport
+//!
+//! The file transport writes the emails to the given directory. The name of the file will be `message_id.txt`.
+//! It can be useful for testing purposes.
+//!
+//! ```rust
+//! use std::env::temp_dir;
+//!
+//! use lettre::transport::file::FileEmailTransport;
+//! use lettre::transport::EmailTransport;
+//! use lettre::email::{EmailBuilder, SendableEmail};
+//!
+//! // Write to the local temp directory
+//! let mut sender = FileEmailTransport::new(temp_dir());
+//! let email = EmailBuilder::new()
+//!                 .to("root@localhost")
+//!                 .from("user@localhost")
+//!                 .body("Hello World!")
+//!                 .subject("Hello")
+//!                 .build()
+//!                 .unwrap();
+//!
+//! let result = sender.send(email);
+//! assert!(result.is_ok());
+//! ```
+//! Example result in `/tmp/b7c211bc-9811-45ce-8cd9-68eab575d695.txt`:
+//!
+//! ```text
+//! b7c211bc-9811-45ce-8cd9-68eab575d695: from=<user@localhost> to=<root@localhost>
+//! To: <root@localhost>
+//! From: <user@localhost>
+//! Subject: Hello
+//! Date: Sat, 31 Oct 2015 13:42:19 +0100
+//! Message-ID: <b7c211bc-9811-45ce-8cd9-68eab575d695.lettre@localhost>
+//!
+//! Hello World!
+//! ```

+//! ## SMTP transport
+//!
