+# Clay - Deno Command Line Parser
+
+Easily convert command line arguments to objects.
+
+## Examples
+
+A simple command with two options, one of which is required.
+```ts
+import { Command, string, number } from "https://deno.land/x/clay/mod.ts";
+
+const cmd = new Command("A simple example.")
+  .required(string, "name", { flags: ["n", "name"], description: "The name." })
+  .optional(number, "age", { flags: ["a", "age"], description: "The age." });
+
+console.log(cmd.run()); // { name: string, age: number | null }
+```
+
+Simple yes / no flag options are supported as well.
+```ts
+import { Command, string, number } from "https://deno.land/x/clay/mod.ts";
+
+const cmd = new Command("A simple example.")
+  .required(string, "file")
+  .flag("overwrite", { aliases: ["o"], description: "Overwrite the file." });
+
+console.log(cmd.run()); // { file: string, overwrite: boolean }
+```
