+## Setup for AngularJS
+
+### Initialization
+
+1. Load the `dist/stackdriver-errors-concat.min.js` JavaScript module.
+
+2. Implement a new [exception handler](https://docs.angularjs.org/api/ng/service/$exceptionHandler) for your AngularJS application:
+
+```JS
+angular.module('yourApp', [])
+
+  .factory('$exceptionHandler', ['$log', '$window', function($log, $window) {
+    var StackdriverErrors = new $window.StackdriverErrorReporter();
+    StackdriverErrors.start({
+      key: '<my-api-key>',
+      projectId: '<my-project-id>',
+      service: '<my-service>',              // (optional)
+      version: '<my-service-version>'       // (optional)
+    });
+
+    return function(exception, cause) {
+      StackdriverErrors.report(exception);
+      $log.warn('Reported error:', exception, cause);
+    };
+  }])
+```
+
+### Usage
+
+Uncaught exception in angular expressions will be reported to Stackdriver Error Reporting using this service.
+
+If you wish, you can manually delegate exceptions, e.g. `try { ... } catch(e) { $exceptionHandler(e); }` or simply `$exceptionHandler(e);`.
