 ### Generating protogen classes
-To generate the Dart code reading the records from results.json,
-and the gRPC server and client code from query.proto,
-run protogen on the .proto files declaring them:
-```
-protoc --dart_out=lib/src/generated -I../common ../common/result.proto
-protoc --dart_out=grpc:lib/src/generated -Ilib/protos -Ithird_party/proto lib/protos/query.proto
-dart format lib/src/generated/query* lib/src/generated/result*
-```
 
-Our gRPC api protocol uses the gRPC api of Pub/Sub from google/pubsub/v1, so we
-need to check out the googleapis protocol buffer definitions and generate them.
-They are not checked into the repository, and must be generated.
-```
-protoc --dart_out=lib/src/generated -I[protobuf checkout]/src [protobuf checkout]/src/google/protobuf/*.proto
-protoc --dart_out=grpc:lib/src/generated -I[googleapis checkout] [googleapis checkout]/google/pubsub/v1/pubsub.proto
-```
+Pre-requisites:
+- Install the protoc compiler: https://developers.google.com/protocol-buffers/docs/downloads
+- Install https://pub.dev/packages/protoc_plugin/install
+- A copy of https://github.com/googleapis/googleapis
+- A copy of https://github.com/protocolbuffers/protobuf
 
+To generate the required Dart files for the protos, run
+`tools/generate_protogen.sh` with the environtment variables
+`GOOGLEAPIS_PATH` and `PROTOBUF_PATH` set to the location of the checkouts
+mentioned above.
 
 ### Staging
 To build the server and deploy to cloud run on staging, run
diff --git a/current_results/tools/generate_protogen.sh b/current_results/tools/generate_protogen.sh
