+# `wit-bindgen` D Bindings Generator
+
+This tool generates [D](https://dlang.org) bindings for a chosen WIT world.
+
+## Usage
+
+To generate bindings with this crate, issue the `d` subcommand to `wit-bindgen`:
+
+```bash
+$ wit-bindgen d [OPTIONS] <WIT>
+```
+
+See the output of `wit-bindgen help d` for available options.
+

+TODO: Flesh out fuller docs (ownership, more usage, examples, etc.)
