can you update the description to match the python image, I think it is simpler:
https://github.com/GoogleCloudPlatform/python-docker/tree/master/runtime

Done.

+is a [docker](https://docker.io) base image for easily running a
+[Dart](https://dartlang.org) application.
+
+It can automatically bundle a Dart application with its dependencies and
+set the default entrypoint with no additional `Dockerfile` instructions.
+
+It is based on [`google/dart`](https://index.docker.io/u/google/dart) base
+image.
+
+## Usage
+
+Create a `Dockerfile` in your Dart application directory with the following
+content:
+
+    FROM google/dart-runtime
+
+To build the a docker image tagged with `my/app` run:
+
+    docker build -t my/app .

[proppy, 2014/07/02 20:55:55]

I would remove the my/ prefix (it is not valid)

[Søren Gjesse, 2014/07/03 10:36:41]

Changed to my-app.

+
+To run this image in a container (assuming it is a server application
+listening in port 8080):
+
+    docker run -d -p 8080:8080 my/app

I would remove the my/ prefix (it is not valid)

[Søren Gjesse, 2014/07/03 10:36:41]

Changed to my-app.

+
+## Sample
+
+See the [sources](/hello) for
+[`google/dart-hello`](https://index.docker.io/u/google/dart-hello) based
+on this image.
+
+## Notes
+
+The image assumes that your application:
+
+- has a the `pubspec.yaml` and `pubspec.lock` files listing its dependencies.
+- has a file named `bin/server.dart` as the entrypoint script.

[proppy, 2014/07/02 20:55:55]

is that standard to have a bin subdirectory in a dart source repo?

[Søren Gjesse, 2014/07/03 10:36:41]

Ye, this it the directory structure we are suggesting. bin/ for server side
code, web/ for client side code and lib/ for shared code.

+- listens on port `8080`
+
+### Example directory laoyout:
+
+    bin
+      server.dart
+    packages
+      ...
+    pubspec.lock
+    pubspec.yaml
+
+When building your application docker image, `ONBUILD` triggers fetch the
+dependencies listed in `pubspec.yaml` and `pubspec.yaml` and cache them
+appropriatly.
