-🚧 _This is presently under heavy construction._
+**Clientele** makes it easy to write superb command-line utilities in Rust that
+follow best practices on all target platforms including Linux, macOS, and
+Windows. It packages and re-exports [`clap`], [`dotenvy`], [`argfile`], and
+[`wild`] into a single easy dependency.
+
+## ✨ Features
+
+- Showcases how to structure a CLI program in Rust (see the [examples](#Examples)).
+- Loads environment variables from `.env` files (using the [`dotenvy`] crate).
+- Expands command-line wildcards (globs) on Windows (using the [`wild`] crate).
+- Expands command-line @argfiles similarly to [`javac`] or Python (using the [`argfile`] crate).
+- Defines a standard set of essential command-line options (using the [`clap`] crate).
+- Supports opting out of any feature using comprehensive feature flags.
+- Adheres to the Rust API Guidelines in its [naming conventions].
+- 100% free and unencumbered public domain software.
