+
+This package provides shared utilities for retries.
+
+## Usage
+
+### Default
+
+By default, each client already has a default retry strategy. The default retry count is 3, and
+only retryable errors will be retried.
+
+[AWS Documentation: Retry behavior](https://docs.aws.amazon.com/sdkref/latest/guide/feature-retry-behavior.html).
+
+```js
+import { S3Client } from "@aws-sdk/client-s3";
+
+const client = new S3Client({}); // default retry strategy included.
+```
+
+### MaxAttempts
+
+If you want to change the number of attempts, you can provide `maxAttempts` configuration during client creation.
+
+```js
+import { S3Client } from "@aws-sdk/client-s3";
+
+const client = new S3Client({ maxAttempts: 4 });
+```
+
+This is recommended because the `StandardRetryStrategy` includes backoff calculation,
+deciding whether an error should be retried, and a retry token counter.
+
+### MaxAttempts and BackoffComputation
+
+If you want to change the number of attempts and use a custom delay
+computation, you can use the `ConfiguredRetryStrategy` from `@smithy/util-retry`.
+
+```js
+import { S3Client } from "@aws-sdk/client-s3";
+import { ConfiguredRetryStrategy } from "@smithy/util-retry";
+
+const client = new S3Client({
+  retryStrategy: new ConfiguredRetryStrategy(
+    4, // max attempts.
+    (attempt: number) => 100 + attempt * 1000 // backoff function.
+  ),
+});
+```
+
+This example sets the backoff at 100ms plus 1s per attempt.
+
+### MaxAttempts and RetryStrategy
+
+If you provide both `maxAttempts` and `retryStrategy`, the `retryStrategy` will
+get precedence as it's more specific.
+
+```js
+import { S3Client } from "@aws-sdk/client-s3";
+import { ConfiguredRetryStrategy } from "@smithy/util-retry";
+
+const client = new S3Client({
+  maxAttempts: 2, // ignored.
+  retryStrategy: new ConfiguredRetryStrategy(
+    4, // used.
+    (attempt: number) => 100 + attempt * 1000 // backoff function.
+  ),
+});
+```
+
+### Further customization
+
+You can implement the `RetryStrategyV2` interface.
