+This document serves as the official spec for those features. As the Web platform evolves,
 we expect some of those features will evolve too or become deprecated.
 
-On the server-side, [Envoy](https://www.envoyproxy.io/) is the official proxy with out-of-box gRPC-Web support. New features will be implemented in Envoy first. For [in-process gRPC-Web support](https://github.com/grpc/grpc-web/blob/master/doc/in-process-proxy.md), we recommend the gRPC-Web module implement only a minimum set of features, e.g. to enable local development. Those features are identified as mandatory features in this doc.
