 Envoy [ALS(access log service)](https://www.envoyproxy.io/docs/envoy/latest/api-v2/service/accesslog/v2/als.proto) provides
 fully logs about RPC routed, including HTTP and TCP.
 
+**If solution initialized and first implemented by Sheng Wu, Hongtao Gao, Lizan Zhou at 17 May. 2019, and presented on KubeCon China 2019.**
+
+SkyWalking is the first open source project introducing this ALS based solution to the world. This provides a new way with very low payload to service mesh, but the same observability.

 You need three steps to open ALS.
-1. Open envoyAccessLogService at istio. See [more](https://github.com/istio/istio/blob/22198bd29b224139b9614fe506e5c07716928031/install/kubernetes/helm/istio/values.yaml#L179)
-on istio helm chart.
-```yaml
-    # Configure envoy gRPC access log service.
-    envoyAccessLogService:
-      enabled: false
-      host: # example: accesslog-service.istio-system
-      port: # example: 15000
-      tlsSettings:
-        mode: DISABLE # DISABLE, SIMPLE, MUTUAL, ISTIO_MUTUAL
-        clientCertificate: # example: /etc/istio/als/cert-chain.pem
-        privateKey: # example: /etc/istio/als/key.pem
-        caCertificates: # example: /etc/istio/als/root-cert.pem

 2. Open SkyWalking [envoy receiver](../backend/backend-receivers.md).
 3. Active ALS k8s-mesh analysis
