+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.

+# plugin
+
+Support for building plugins in Dart.
+
+This project defines a simple framework for defining plugins. A _plugin_ is the
+unit of extensibility for a host application.
+
+An _extension point_ represents one way of extending the host application. For
+example, a file viewer application might define an extension point to allow
+viewers for new file types to be added to the application.
+
+The host application must provide at least one extension point that plugins can
+extend. Every extension point must have a unique name associated with it, and
+should specify the type of the objects that will be accepted as extensions. In
+the example above, the extension point might require that all extensions
+implement the interface FileViewer.
+
+Any plugin can define extension points that other plugins can extend. The host
+application contributes its own extension point(s) by defining a plugin.
+
+An _extension_ is an object that a plugin associates with a particular extension
+point. To continue the example, a plugin that supports the viewing of .gif files
+would create an instance of GifFileViewer, a class that implements FileViewer.
+
+The framework in this package then connects the defined extensions with the
+defined extension points so that the separately contributed plugins can
+coordinate to accomplish the larger goal.
