+## 0.9.0-alpha+3

+> NOTE: This code is considered production quality, but depends on angular:
+> 5.0.0-alpha+3. The alpha tag represents the evolving nature of the AngularDart
+> api, not code quality (5.0.0-alpha+3 is used in production Google apps).
+
+**NOTE**: As of `angular 5.0.0-alpha+1` [`dependency_overrides`][dep_overrides]
+are **required**:
+
+```yaml
+dependency_overrides:
+  analyzer: ^0.31.0-alpha.1
+```
+
+This is because Angular is starting to use and support the Dart 2.0.0 SDK, which
+is evolving. We expect to no longer require overrides once we are at a beta
+release, but this is unlikely until sometime in early 2018.

+## Package [build_runner] support
+
+Version 0.9.0-alpha+3 added experimental support for users of package
+build_runner. To build your project with build_runner:
+
+1. Add two `dev_dependencies` to your packages pubspec.yaml file:
+  ```
+  dev_dependencies:
+    build_runner: ^0.7.0
+    build_web_compilers: ^0.1.1
+  ```
+2. Run `pub get --no-precompile` (avoids pre-compiling unused transformers).
+3. Build your package:
+  ```
+  pub run build_runner build
+  ```
+  Or run a local development server:
+  ```
+  pub run build_runner serve
+  ```
