+First, follow the instructions in [../README.md](../README.md) to install the Protocol Buffer Compiler (protoc).
+
+Then, install the Dart Protocol Buffer plugin as described [here](https://github.com/dart-lang/dart-protoc-plugin#how-to-build-and-use).
+Note, the executable `bin/protoc-gen-dart` must be in your `PATH` for `protoc` to find it.
+
+Build the Dart samples in this directory with `make dart`.
+
+To run the examples:
+
+```sh
+$ dart add_person.dart addessbook.data
+$ dart list_people.dart addressbook.data
+```
+
+The two programs take a protocol buffer encoded file as their parameter.
+The first can be used to add a person to the file. The file is created
+if it does not exist. The second displays the data in the file.
