   definitions are converted to `.pb.go` implementations.
 - A mock implementation of the Trillian gRPC API (in `trillian/mockclient`) is
   created with [GoMock](https://github.com/golang/mock).
+- Some enums have string-conversion methods (satisfying the `fmt.Stringer`
+   interface) created using the
+   [stringer](https://godoc.org/golang.org/x/tools/cmd/stringer) tool (`go get
+   golang.org/x/tools/cmd/stringer`).
 
 Re-generating mock or protobuffer files is only needed if you're changing
-the original files; if you do, you'll need to install the prerequisites:
+the original files. The recommended way to do this is by using the Docker
+image used by the Cloud Build:
 
-- tools written in `go` can be installed with a single run of `go install`
-  (courtesy of [`tools.go`](./tools/tools.go) and `go.mod`).
-- `protoc` tool: you'll need [version 3.20.1](https://github.com/protocolbuffers/protobuf/releases/tag/v3.20.1) installed, and `PATH` updated to include its `bin/` directory.
+```shell
+docker build -f ./integration/Dockerfile -t ctgo-builder .
+docker run -it --mount type=bind,src="$(pwd)",target=/src ctgo-builder /bin/bash -c "cd /src; ./scripts/install_deps.sh; go generate -x ./..."
+```
+
+These commands first create a docker image from the Dockerfile in this repo, and
+then launch a container based on this image with the local directory mounted. The
+correct versions of the tools are determined using the `go.mod` file in this repo,
+and these tools are installed. Finally, all of the generated files are regenerated
+and Docker exits.
+
+Alternatively, you can install the prerequisites locally:
 
-With tools installed, run the following:
+  - a series of tools, using `go install` to ensure that the versions are
+    compatible and tested:
+
+    ```
+    cd $(go list -f '{{ .Dir }}' github.com/google/certificate-transparency-go); \
+    go install github.com/golang/mock/mockgen; \
+    go install google.golang.org/protobuf/proto; \
+    go install google.golang.org/protobuf/cmd/protoc-gen-go; \
