+ForumOne JavaScript Coding Style (Angular Edition)
+==================================================
+
+See [forumone/javascript](https://github.com/forumone/javascript) on Github for a longer intro.
+
+For best results, mix with a base style guide of your choice. We recommend `eslint-config-forumone-es5`:
+
+```js
+exports.extends = [
+  'forumone-es5',
+  'forumone-angular',
+];
+```
+
+Requirements
+------------
+
+This package depends on both `eslint` and `eslint-plugin-angular`.
+
+Entry Points
+------------
+
+### `forumone-angular/legacy`
+
+For retrofitting existing Angular apps. This config adds some simple lints around DI injection style, unused parameters, and holding on to the return of `angular.module()`.
+
+### `forumone-angular`
+
+The default configuration. This builds on the legacy config and bans deprecated Angular functionality.
+
+It also warns about patterns that go against best practices, such as scope event typos, naming conventions, and having more than one component per file.
+
+### `forumone-angular/strict`
+
+Like the default, but all warnings are hard errors.
