+//! `ICU` is the main meta-package of the `ICU4X` project.
+//!
+//! It provides a comperhensive selection of Unicode Internationalization Components
+//! in their canonical configurations intended to enable software
+//! internationalization capabilities.
+//!
+//! The package is provided for convenience and users are encouraged
+//! to fine-tune components with the features they need.
+//!
+//! The package does not bring any unique functionality. Users
+//! can achieve the exact same by manually including the dependent
+//! components with pre-selected features.
+//!
+//! # Data Provider
+//!
+//! Most of Unicode functionality relies on data which has to be provided
+//! to the APIs.
+//!
+//! `ICU4X` project uses a concept of [`DataProvider`] - a service used to
+//! handle data management.
+//!
+//! There can be many different heuristics for handling data management and
+//! this meta-package does not supply any default `DataProvider`.
+//!
+//! When using `ICU4X` users are expected to decide which provider they want to use
+//! and instrument it to point at the correct location where the data files are stored.
+//!
+//! In the following examples the [`FsDataProvider`] is used, which is a local file-system
+//! service using synchronous I/O to fetch data stored on the hard drive.
+//!
+//! # Examples
+//!
+//! ```
+//! use icu::locale::LanguageIdentifier;
+//! use icu::datetime::{DateTimeFormat, date::MockDateTime, options::style};
+//! use icu_fs_data_provider::FsDataProvider;
+//!
+//! let provider = FsDataProvider::try_new("./tests/fixtures/data/icu4x")
+//!     .expect("Loading file from testdata directory");
+//!
+//! let langid: LanguageIdentifier = "en".parse()
+//!     .expect("Failed to parse a Language Identifier.");
+//!
+//! let options = style::Bag {
+//!     date: Some(style::Date::Long),
+//!     time: Some(style::Time::Medium),
+//!     ..Default::default()
+//! };
+//!
+//! let dtf = DateTimeFormat::try_new(langid, &provider, &options.into())
+//!     .expect("Failed to create DateTimeFormat instance.");
+//!
+//! let date: MockDateTime = "2020-09-12T12:35:00".parse()
+//!     .expect("Failed to parse date.");
+//!
+//! let formatted_date = dtf.format(&date);
+//! assert_eq!(formatted_date.to_string(), "September 12, 2020 \'at\' 12:35:00 PM");
