+Want to contribute? Great! First, read this page (including the small print at
+the end).
+
+### Before you contribute
+Before we can use your code, you must sign the
+[Google Individual Contributor License Agreement](https://cla.developers.google.com/about/google-individual)
+(CLA), which you can do online. The CLA is necessary mainly because you own the
+copyright to your changes, even after your contribution becomes part of our
+codebase, so we need your permission to use and distribute your code. We also
+need to be sure of various other things—for instance that you'll tell us if you
+know that your code infringes on other people's patents. You don't have to sign
+the CLA until after you've submitted your code for review and a member has
+approved it, but you must do it before we can put your code into our codebase.
+
+Before you start working on a larger contribution, you should get in touch with
+us first through the issue tracker with your idea so that we can help out and
+possibly guide you. Coordinating up front makes it much easier to avoid
+frustration later on.
+
+### Code reviews
+All submissions, including submissions by project members, require review.

+This package exposes the `StreamChannel` interface, which represents a two-way
+communication channel. Each `StreamChannel` exposes a `Stream` for receiving
+data and a `StreamSink` for sending it. 
+
+`StreamChannel` helps abstract communication logic away from the underlying
+protocol. For example, the [`test`][test] package re-uses its test suite
+communication protocol for both WebSocket connections to browser suites and
+Isolate connections to VM tests.
+
+[test]: https://pub.dartlang.org/packages/test
+
+This package also contains utilities for dealing with `StreamChannel`s and with
+two-way communications in general. For documentation of these utilities, see
+[the API docs][api].
