+Want to contribute? Great! First, read this page (including the small print at

+
+### 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.

+A package that defines a common class, [`PackageResolver`][PackageResolver], for
+defining how to resolve `package:` URIs. This class may be based on the current
+isolate's package resolution strategy, but it may also be explicitly defined by
+the user—for example, you could create a resolver that represents the strategy
+used to compile a `.dart.js` file.
+
+[PackageResolver]: https://www.dartdocs.org/documentation/package_resolver/latest/package_resolver/PackageResolver-class.html
+
+The Dart VM provides two mutually exclusive means of resolving `package:` URIs:
+a **package spec** and a **package root**.
+
+* A package spec usually comes in the form of a `.packages` file on the
+  filesystem. It defines an individual root URL for each package name, so that
+  `package:$name/$path` resolves to `$root/$path`.
+
+* A package root is a single URL that acts as the base for all `package:` URIs,
+  so that `package:$name/$path` resolves to `$base/$name/$path`.
+
+This normalizes access to these resolution schemes, and makes it easy for code
+to resolve package URIs no matter where the resolution information comes from.
