+### Clients
+
+We provide a variety of possible clients to use when generating your `openapi-ts` client. The following are available:
+
+- `angular`: An [Angular](https://angular.io/) client using [RxJS](https://rxjs.dev/).
+- `axios`: An [Axios](https://axios-http.com/docs/intro) client.
+- `fetch`: A [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) client.
+    > NOTE: The Fetch API is experimental in Node.js 18+ and was stabilized in [Node.js v21](https://nodejs.org/docs/latest-v21.x/api/globals.html#fetch)
+- `node`: A [Node.js](https://nodejs.org/) client using [node-fetch](https://www.npmjs.com/package/node-fetch).
+- `xhr`: A [XMLHttpRequest](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest) client.
+
 ### Formatting
 
 By default, `openapi-ts` will automatically format your client according to your project configuration. To disable automatic formatting, set `format` to false
