 The IngressController is an implementation of [Kubernetes ingress controller](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/), it watches Kubernetes Ingress, Service, Endpoints, and Secrets then translates them to Easegress HTTP server and pipelines.

+### Additional Annotations
+
+When defining your `Ingress` configurations, you can use the following `easegress` specific annotations for added customization:
+
+- **Load Balancing**: `easegress.ingress.kubernetes.io/proxy-load-balance`
+- **Header Hash Key for Load Balancing**: `easegress.ingress.kubernetes.io/proxy-header-hash-key`
+- **Forwarding Key**: `easegress.ingress.kubernetes.io/proxy-forward-key`
+- **Server Response Maximum Size**: `easegress.ingress.kubernetes.io/proxy-server-max-size`
+- **Proxy Timeout**: `easegress.ingress.kubernetes.io/proxy-timeout`
+
+Please refer to the [Proxy Server Pool Spec](../07.Reference/7.02.Filters.md#proxyserverpoolspec) and [Load Balance Spec](../07.Reference/7.02.Filters.md#proxyloadbalancespec) to get the details of the corresponding annotations.
+
+These annotations provide additional configurations to optimize the behavior and performance of your ingress controllers in different scenario.
