+### Retries
+
+By default API requests are retried up to 15 times on 429 and 5xx errors and credential requests are retried to 3 times on 429 and 5xx errors. In both instances they will wait a minimum of 100 milliseconds between requests and up to a maximum of 
+
+In order to change the behavior for API requests, pass a `retryParams` object in the `OpenFgaClient` constructor with a `maxRetry` property to control the amount of retries and a `minWaitInMs` to control the minimum wait time between retried requests.
+
+```javascript
+const { OpenFgaClient } = require('@openfga/sdk'); // OR import { OpenFgaClient } from '@openfga/sdk';
+
+const fgaClient = new OpenFgaClient({
+  apiUrl: process.env.FGA_API_URL, // required
+  storeId: process.env.FGA_STORE_ID, // not needed when calling `CreateStore` or `ListStores`
+  authorizationModelId: process.env.FGA_AUTHORIZATION_MODEL_ID, // Optional, can be overridden per request
+  retryParams: {
+    maxRetry: 3, // retry up to 3 times on API requests
+    minWaitInMs: 250 // wait a minimum of 250 milliseconds between requests
+  }
+});
+```
