-There is an experimental support for [gogo
-protobuf](https://github.com/gogo/protobuf) plugin for `go`. Use the following
-command to generate `gogo`-compatible validation code:
-
-```sh
-protoc \
-  -I . \
-  -I ${GOPATH}/src \
-  -I ${GOPATH}/src/github.com/envoyproxy/protoc-gen-validate \
-  --gogofast_out=":../generated"\

-Gogo support has the following limitations:
-- only `gogofast` plugin is supported and tested, meaning that the fields
-  should be properly annotated with `gogoproto` annotations;
-- `gogoproto.nullable` is supported on fields;
-- `gogoproto.stdduration` is supported on fields;
-- `gogoproto.stdtime` is supported on fields;
