-## Additional features in the new SDK
 
-1. **Retry configuration**
-
-The retry configuration allows you to specify how the SDK should handle retries for failed requests. You can configure the retry strategy, initial interval, maximum interval, exponent, and maximum elapsed time.
-
-Here is an example of how to configure retries:
-
-```csharp
-var sdk = new Apideck(
-    retryConfig: new RetryConfig(
-        strategy: RetryConfig.RetryStrategy.BACKOFF,
-        backoff: new BackoffStrategy(
-            initialIntervalMs: 1L,
-            maxIntervalMs: 50L,
-            maxElapsedTimeMs: 100L,
-            exponent: 1.1
-        ),
-        retryConnectionErrors: false
-    ),
-    apiKey: "<YOUR_BEARER_TOKEN_HERE>",
-    consumerId: "test-consumer",
-    appId: "your-app-id"
-);
-```
-
-For more information about retry configuration, please refer to the [Retry Configuration Documentation](https://github.com/apideck-libraries/sdk-csharp/tree/main?tab=readme-ov-file#retries).
