+Chariot's API can be accessed via SDKs for several popular languages.
+The SDKs are generated from our OpenAPI 3 [specification](https://github.com/chariot-giving/chariot-openapi/blob/main/specs).
+The JSON specification may be helpful if you are looking to use a language we haven't implemented yet!
+
+Our APIs are stable but we're just getting started with these SDKs,
+so some things might change in future versions.
+If you find them useful or have feedback, [please let us know]((mailto:support@givechariot.com))!
+
+Using an SDK can speed up your integration by providing an implementation for pagination, serialization, timeouts, retries, and error handling.
+
+## Node
+
+Install our Node SDK with `npm` or `yarn`.
+The source is on [GitHub](https://github.com/chariot-giving/typescript-sdk).
+Request parameters, response bodies, and error details are all typed with Typescript.
+
+```sh
+$ npm install --save @chariot-giving/typescript-sdk
+# or
+$ yarn add @chariot-giving/typescript-sdk
+```
+
+## More coming soon!
+
+Let us know if you'd like to be an early adopter or if there's another language we should support.
