+//! # Grammalecte Rust Client
+//!
+//! This crate is a Rust client to the Grammalecte server API.
+//!
+//! Grammalecte is an Open Source software that allows to do
+//! french spell-checking.
+//!
+//! ## Integrated server
+//! The optional feature `embedded-server` allows you to spin up an
+//! temporary web server that will act as Grammalecte backend, instead
+//! of targetting an existing instance:
+//!
+//! ```rust,no_run
+//! use grammalecte_client::GrammalecteClient;
+//!
+//! let msg = "Les ange sont inssuportables!";
+//! let res = GrammalecteClient::start_server()
+//!             .unwrap()
+//!             .spell_check(msg)
+//!             .await
+//!             .unwrap();
+//! println!("RESULT = {:#?}", res);
+//! ```
+//!
+//! ## Suggestion
+//! You can also ask Grammalecte to give you valid alternatives words:
+//! ```rust,no_run
+//! let res = GrammalecteClient::start_server()
+//!             .unwrap()
+//!             .suggest("bonjou")
+//!             .await
+//!             .unwrap();
+//! assert!(res.suggestions.contains(&"bonjour".to_string()));
+//! println!("RESULT = {:#?}", res);
+//! ```
