 ## Usage
 
+### getOptions(TObject)
+
+Transform a whole TypeBox object into yargs options object.
+
+```typescript
+import { type Static, Type } from "@sinclair/typebox";
+import yargs from "yargs";
+import { hideBin } from "yargs/helpers";
+import { getOptions } from "yargs-typebox";
+
+const schema = Type.Object({
+  page: Type.Number({ description: "page number" }),
+  size: Type.Number({ description: "page size", default: 10 }),
+  query: Type.Optional(Type.String()),
+  sort: Type.Optional(
+    Type.Array(Type.Union([Type.Literal("id"), Type.Literal("createdAt")])),
+  ),
+  order: Type.Union([Type.Literal("asc"), Type.Literal("desc")], {
+    default: "asc",
+    implies: ["sort"],
+  }),
+  pretty: Type.Boolean({ description: "pretty print" }),
+  count: Type.Any({ description: "count", count: true }),
+});

+### getOption(TSchema)
+
+Transform a single TypeBox schema into yargs option.
