+Also make sure you have the following in your `package.json`:
+
+```json
+{
+  "dependencies": {
+    "google-protobuf": "^3.6.1",
+    "grpc-web-client": "0.7.0",
+    "browser-headers": "^0.4.1"
+  },
+  "devDependencies": {
+    "@bazel/karma": "^0.21.0",
+    "@bazel/typescript": "^0.21.0",
+    "@types/google-protobuf": "^3.2.7",
+    "typescript": "^3.1.1"
+  }
+}
+```
 
-Now in your `BUILD.bazel`:
+> Run `yarn install` to generate the `yarn.lock` file.
+
+Finally, in your `BUILD.bazel`:
 
 ```python
 load("@ts_protoc_gen//:defs.bzl", "typescript_proto_library")
 
-filegroup(
-  name = "proto_files",
-  srcs = glob(["*.proto"]),
-)
-
 proto_library(
-  name = "proto",
+  name = "test_proto",
   srcs = [
-    ":proto_files",
+    "test.proto",
   ],
 )
 
 typescript_proto_library(
-  name = "generate",
-  proto = ":proto",
+  name = "test_ts_proto",
+  proto = ":test_proto",
 )
 ```
 
+You can use the `test_ts_proto` as a `dep` in other `ts_library` targets. However, you will need to
+include `google-protobuf`, `grpc-web-client`, and `browser-headers` at runtime yourself. See 
+`//test/bazel:pizza_service_proto_test_suite` for an example.
