+# Seed TypeScript Library
+
+[![fern shield](https://img.shields.io/badge/%F0%9F%8C%BF-Built%20with%20Fern-brightgreen)](https://buildwithfern.com?utm_source=github&utm_medium=github&utm_campaign=readme&utm_source=Seed%2FTypeScript)
+[![npm shield](https://img.shields.io/npm/v/@fern/license)](https://www.npmjs.com/package/@fern/license)
+
+The Seed TypeScript library provides convenient access to the Seed API from TypeScript.
+
+## Installation
+
+```sh
+npm i -s @fern/license
+```
+
+## Reference
+
+A full reference for this library is available [here](./reference.md).
+
+## Usage
+
+Instantiate and use the client with the following:
+
+```typescript
+import { SeedLicenseClient } from "@fern/license";
+
+const client = new SeedLicenseClient({ environment: "YOUR_BASE_URL" });
+await client.get();
+```
+
+## Exception Handling
+
+When the API returns a non-success status code (4xx or 5xx response), a subclass of the following error
+will be thrown.
+
+```typescript
+import { SeedLicenseError } from "@fern/license";
+
+try {
+    await client.get(...);
+} catch (err) {
+    if (err instanceof SeedLicenseError) {
+        console.log(err.statusCode);
+        console.log(err.message);
+        console.log(err.body);
+    }
+}
+```
+
+## Advanced
+
+### Retries
+
+The SDK is instrumented with automatic retries with exponential backoff. A request will be retried as long
+as the request is deemed retriable and the number of retry attempts has not grown larger than the configured
+retry limit (default: 2).
+
+A request is deemed retriable when any of the following HTTP status codes is returned:
+
+-   [408](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/408) (Timeout)
+-   [429](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/429) (Too Many Requests)
+-   [5XX](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/500) (Internal Server Errors)
+
+Use the `maxRetries` request option to configure this behavior.
+
+```typescript
+const response = await client.get(..., {
+    maxRetries: 0 // override maxRetries at the request level
+});
+```
+
+### Timeouts
+
+The SDK defaults to a 60 second timeout. Use the `timeoutInSeconds` option to configure this behavior.
+
+```typescript
+const response = await client.get(..., {
+    timeoutInSeconds: 30 // override timeout to 30s
+});
+```
+
+### Aborting Requests
+
+The SDK allows users to abort requests at any point by passing in an abort signal.
+
+```typescript
+const controller = new AbortController();
+const response = await client.get(..., {
+    abortSignal: controller.signal
+});
+controller.abort(); // aborts the request
+```
+
+### Runtime Compatibility
+
+The SDK defaults to `node-fetch` but will use the global fetch client if present. The SDK works in the following
+runtimes:
+
+-   Node.js 18+
+-   Vercel
+-   Cloudflare Workers
+-   Deno v1.25+
+-   Bun 1.0+
+-   React Native
+
+### Customizing Fetch Client
+
+The SDK provides a way for your to customize the underlying HTTP client / Fetch function. If you're running in an
+unsupported environment, this provides a way for you to break glass and ensure the SDK works.
+
+```typescript
+import { SeedLicenseClient } from "@fern/license";
+
+const client = new SeedLicenseClient({
+    ...
+    fetcher: // provide your implementation here
+});
+```
+
+## Contributing
+
+While we value open-source contributions to this SDK, this library is generated programmatically.
+Additions made directly to this library would have to be moved over to our generation code,
+otherwise they would be overwritten upon the next generated release. Feel free to open a PR as
+a proof of concept, but know that we will not be able to merge it as-is. We suggest opening
+an issue first to discuss with us!
+
+On the other hand, contributions to the README are always very welcome!
