+//! dialoguer is a library for Rust that helps you build useful small
+//! interactive user inputs for the command line. It provides utilities
+//! to render various simple dialogs like confirmation prompts, text
+//! inputs and more.
+//!
+//! Best paired with other libraries in the family:
+//!
+//! * [indicatif](https://docs.rs/indicatif)
+//! * [console](https://docs.rs/console)
+//!
+//! # Crate Contents
+//!
+//! * Confirmation prompts
+//! * Input prompts (regular and password)
+//! * Input validation
+//! * Selections prompts (single and multi)
+//! * Fuzzy select prompt
+//! * Other kind of prompts
+//! * Editor launching
+//!
+//! # Crate Features
+//!
+//! The following crate features are available:
+//! * `editor`: enables bindings to launch editor to edit strings
+//! * `fuzzy-select`: enables fuzzy select prompt
+//! * `history`: enables input prompts to be able to track history of inputs
+//! * `password`: enables password input prompt
+//! * `completion`: enables ability to implement custom tab-completion for input prompts
+//!
+//! By default `editor` and `password` are enabled.
