 ## Background
 
-A50: gRPC xDS Outlier Detection Support is a spec for gRPC to support xDS Outlier Detection. The current implementation only offers debug and trace logging in terms of visibility, which can be insufficient for understanding and diagnosing decision making in large-scale production systems. 
+[A50: gRPC xDS Outlier Detection Support](https://github.com/grpc/proposal/blob/master/A50-xds-outlier-detection.md) is a spec for gRPC to support xDS Outlier Detection. The current implementation only offers debug and trace logging in terms of visibility, which can be insufficient for understanding and diagnosing decision making in large-scale production systems. 
 
 Using A79: Non-per-call Metrics Architecture, it is possible to add granular metrics to make visibility into outlier detection easy for service owners utilizing gRPC.

 ## Proposal
 
-A79’s non-per-call metrics architecture fits perfectly into the metrics reporting solution. We propose to aim for parity where appropriate with Envoy’s xDS implementation for metrics to be collected in gRPC
