+Already using [TypeSpec](https://typespec.io) to describe your API and generate your OpenAPI spec, JSON schema, etc.? You can use [`typespec-fast-check`](https://github.com/TomerAberbach/typespec-fast-check) to also generate fast-check arbitraries from your TypeSpec files.
+
+For example, the following TypeSpec file:
+
+```tsp
+model Person {
+  /** The person's first name. */
+  firstName: string;
+
+  /** The person's last name. */
+  lastName: string;
+
+  /** Age in years which must be equal to or greater than zero. */
+  @minValue(0) age: int32;
+
+  /** Person address */
+  address: Address;
+
+  /** List of nick names */
+  nickNames?: string[];
+
+  /** List of cars person owns */
+  cars?: Car[];
+}
+
+/** Represents an address */
+model Address {
+  street: string;
+  city: string;
+  country: string;
+}
+model Car {
+  /** Kind of car */
+  kind: "ev" | "ice";
+
+  /** Brand of the car */
+  brand: string;
+
+  /** Model of the car */
+  `model`: string;
+}
+```
+
+Can generate the following fast-check arbitraries file:
+
+```js
+// Generated from TypeSpec using `typespec-fast-check`
+
+import fc from 'fast-check';
+
+export const Car = fc.record({
+  /** Kind of car */
+  kind: fc.constantFrom('ev', 'ice'),
+  /** Brand of the car */
+  brand: fc.string(),
+  /** Model of the car */
+  model: fc.string(),
+});
+
+/** Represents an address */
+export const Address = fc.record({
+  street: fc.string(),
+  city: fc.string(),
+  country: fc.string(),
+});
+
+export const Person = fc.record(
+  {
+    /** The person's first name. */
+    firstName: fc.string(),
+    /** The person's last name. */
+    lastName: fc.string(),
+    /** Age in years which must be equal to or greater than zero. */
+    age: fc.nat(),
+    /** Person address */
+    address: Address,
+    /** List of nick names */
+    nickNames: fc.array(fc.string()),
+    /** List of cars person owns */
+    cars: fc.array(Car),
+  },
+  {
+    requiredKeys: ['firstName', 'lastName', 'age', 'address'],
+  },
+);
