+# Stripe Demo Fern Configuration
+
+This repository contains the Stripe Demo Fern configuration: 
+  - [OpenAPI](./openapi.yaml)
+  - [Generators configuration](./generators.yml)
+
+## Validating your API Definition
+
+To validate the API, run: 
+```bash
+npm install -g fern-api # only required once
+fern check
+```
+
+## Updating your Docs
+
+View your generated documentation website at [stripe.docs.buildwithfern.com](https://stripe.docs.buildwithfern.com).
+
+### Local Development server
+
+To run a local development server with hot-reloading you can run the following command
+
+```bash
+fern docs dev
+```
+
+### Hosted URL
+
+Documentation is automatically updated when you push to main via the `fern generate` command
+
+```bash
+npm install -g fern-api # only required once
+fern generate --docs
+```
+
+## Generate the TypeScript SDK
+
+To update the TypeScript SDK, simply run the `Release Node.js SDK` GitHub Action with the desired version for the release. Under the hood, this leverages the Fern CLI: 
+
+```sh
+fern generate --group node-sdk
+```
