 //! # urlshortener
 //!
 //! An easy library for retrieving short urls.
 //!
-//! ## Usage
-//!
-//! Creating a short URL via a specified provider is very simple:
-//!
-//! ```rust,no_run
-//! use urlshortener::{providers::Provider, client::UrlShortener};
-//!
-//! let us = UrlShortener::new().unwrap();
-//! let short_url = us.generate("https://my-long-url.com", &Provider::IsGd);
-//! assert!(short_url.is_ok());
-//! ```
-//!
-//! Or attempting all URL shorteners until one is successfully generated:
-//!
-//! ```rust,no_run
-//! use urlshortener::client::UrlShortener;
-//!
-//! let us = UrlShortener::new().unwrap();
-//! let short_url = us.try_generate("https://my-long-url.com", None);
-//! assert!(short_url.is_ok());
-//! ```
-//! In order to use service with authentication use the appropriate provider directly:
-//!
-//! ```rust,no_run
-//! use urlshortener::{ client::UrlShortener, providers::Provider };
-//!
-//! let us = UrlShortener::new().unwrap();
-//! let key = "MY_API_KEY";
-//! let short_url = us.generate("https://my-long-url.com", &Provider::GooGl { api_key:
-//! key.to_owned() });
-//! assert!(short_url.is_ok());
-//! ```
