+//! # About Boa
+//!
+//! Boa is an open-source, experimental ECMAScript Engine written in Rust for lexing, parsing and
+//! executing ECMAScript/JavaScript. Currently, Boa supports some of the [language][boa-conformance].
+//! More information can be viewed at [Boa's website][boa-web].

+//! Try out the most recent release with Boa's live demo [playground][boa-playground].

+//! # Example: Adding Web API's Console Object
+//!
+//! 1. Add **boa_runtime** as a dependency to your project along with **boa_engine**.
+//!
+//! ```
+//! use boa_engine::{ Context, Source, property::Attribute };
+//! use boa_runtime::Console;
+//!
+//! // Create the context.
+//! let mut context = Context::default();
+//!
+//! // Initialize the Console object.
+//! let console = Console::init(&mut context);
+//!
+//! // Register the console as a global property to the context.
+//! context
+//!     .register_global_property(Console::NAME, console, Attribute::all())
+//!     .expect("the console object shouldn't exist yet");
+//!
+//! // JavaScript source for parsing.
+//! let js_code = "console.log('Hello World from a JS code string!')";
+//!
+//! // Parse the source code
+//! match context.eval_script(Source::from_bytes(js_code)) {
+//!     Ok(res) => {
+//!         println!(
