-# Building with Bazel
-
-This guide explains how to build and test Angular apps with Bazel.
-
-
-<div class="alert is-helpful">
-
-This guide assumes you are already familiar with developing and building Angular applications using the [CLI](cli).
-
-It describes features which are part of Angular Labs, and are not considered a stable, supported API.
-
-</div>
-
-## Using Bazel with the Angular CLI
-
-The `@angular/bazel` package provides a builder that allows Angular CLI to use Bazel as the build tool.
-
-To opt-in an existing application, run
-
-```sh
-ng add @angular/bazel
-```
-
-To use Bazel in a new application, first install `@angular/bazel` globally
-
-```sh
-npm install -g @angular/bazel
-```
-
-then create the new application with
-
-```sh
-ng new --collection=@angular/bazel
-```
-
-Now when you use Angular CLI build commands such as `ng build` and `ng serve`,
-Bazel is used behind the scenes.
-Outputs from Bazel appear in the `dist/bin` folder.
-
-> The command-line output includes extra logging from Bazel.
-> We plan to reduce this in the future.
-
-### Removing Bazel
-
-If you need to opt-out from using Bazel, you can restore the backup files:
-
-- `/angular.json.bak` replaces `/angular.json`
-
-## Advanced configuration
-
-<div class="alert is-helpful">
-
-Editing the Bazel configuration may prevent you opting out of Bazel.
-Custom behaviors driven by Bazel won't be available in other Builders.
-
-This section assumes you are familiar with [Bazel](https://docs.bazel.build).
-
-</div>
-
-You can manually adjust the Bazel configuration to:
-
-* customize the build steps
-* parallellize the build for scale and incrementality
-
-Create the initial Bazel configuration files by running the following command:
-
-```sh
-ng build --leaveBazelFilesOnDisk
-```
-
-Now you'll find new files in the Angular workspace:
-
-* `/WORKSPACE` tells Bazel how to download external dependencies.
-* `/BUILD.bazel` and `/src/BUILD.bazel` tell Bazel about your source code.
-
-You can find a full-featured example with custom Bazel configurations at https://github.com/bazelbuild/rules_nodejs/tree/master/examples/angular.
-
-Documentation for using Bazel for frontend projects is linked from https://docs.bazel.build/versions/master/bazel-and-javascript.html.
-
-
-
-## Running Bazel directly
-
-In some cases you'll want to bypass the Angular CLI builder, and run the Bazel CLI directly.
-The Bazel tool is managed by the `@bazel/bazelisk` package (similar to how Node.js can be managed by `nvm`).
-You can install it globally to get the `bazelisk` command in your path, or use `$(npm bin)/bazelisk` in place of bazelisk below.
-
-The common commands in Bazel are:
-
-* `bazelisk build [targets]`: Compile the default output artifacts of the given targets.
-* `bazelisk test [targets]`: For whichever `*_test` targets are found in the patterns, run the tests.
-* `bazelisk run [target]`: Compile the program represented by target, and then run it.
-
-To repeat the command any time the inputs change (watch mode), replace `bazelisk` with `ibazel` in these commands.
-
-The output locations are printed in the output.
-
-Full documentation for the Bazel CLI is at https://docs.bazel.build/versions/master/command-line-reference.html.
-
-
-## Querying the build graph
-
-Because Bazel constructs a graph out of your targets, you can find lots of useful information.
-
-Using the graphviz optional dependency, you'll have a program `dot`, which you can use with `bazel query`:
-
-```bash
-$ bazel query --output=graph ... | dot -Tpng > graph.png
-```
-
-See https://docs.bazel.build/versions/master/query-how-to.html for more details on `bazel query`.
-
-
-## Customizing `BUILD.bazel` files
-
-"Rules" are like plugins for Bazel. Many rule sets are available. This guide documents the ones maintained by the Angular team at Google.
-
-Rules are used in `BUILD.bazel` files, which are markers for the packages in your workspace. Each `BUILD.bazel` file declares a separate package to Bazel, though you can have more coarse-grained distributions so that the packages you publish (for example, to `npm`) can be made up of many Bazel packages.
-
-In the `BUILD.bazel` file, each rule must first be imported, using the `load` statement. Then the rule is called with some attributes, and the result of calling the rule is that you've declared to Bazel how it can derive some outputs given some inputs and dependencies. Then later, when you run a `bazel` command line, Bazel loads all the rules you've declared to determine an absolute ordering of what needs to be run. Note that only the rules needed to produce the requested output will actually be executed.
-
-A list of common rules for frontend development is documented in the README at https://github.com/bazelbuild/rules_nodejs/.

+<div class="alert is-important">
+
+For now, it is not recommended to publish Ivy libraries to NPM because Ivy generated code is not backward compatible with View Engine, so apps using View Engine will not be able to consume them. Furthermore, the internal Ivy instructions are not yet stable, which can potentially break consumers using a different Angular version from the one used to build the library.
+
+When a published library is used in an Ivy app, the Angular CLI will automatically convert it to Ivy using a tool known as the Angular compatibility compiler (`ngcc`). Thus, by publishing your libraries using the View Engine compiler ensures that they can be transparently consumed by both View Engine and Ivy apps.

-Support for IE 9 and 10 has been deprecated and will be removed in a future version.
+Support for IE 9 and 10 has been deprecated, as well as support for IE Mobile. These will be dropped in a future version.
 Supporting outdated browsers like these increases bundle size, code complexity, and test load, and also requires time and effort that could be spent on improvements to the framework.
 For example, fixing issues can be more difficult, as a straightforward fix for modern browsers could break old ones that have quirks due to not receiving updates from vendors.
 
 The final decision was made on three key points:
-* __Vendor support__: Microsoft dropped support of IE 9 and 10 on 1/12/16, meaning they no longer provide security updates or technical support.
-* __Usage statistics__: We looked at usage trends for IE 9 and 10 from various sources and all indicated that usage percentages were extremely small (fractions of 1%).
-* __Feedback from partners__: We also reached out to some of our Angular customers and none expressed concern about dropping IE 9 and 10 support.

 {@a setup-the-form-model}
 
-## Form model setup
-
-Reactive and template-driven forms both use a form model to track value changes between Angular forms and form input elements. The examples below show how the form model is defined and created.
-
 ### Setup in reactive forms
 
-Here's a component with an input field for a single control implemented using reactive forms.
+With reactive forms, you define the form model directly in the component class.
+The `[formControl]` directive links the explicitly created `FormControl` instance to a specific form element in the view, using an internal value accessor.
+
+The following component implements an input field for a single control, using reactive forms. In this example, the form model is the `FormControl` instance.
 
 <code-example path="forms-overview/src/app/reactive/favorite-color/favorite-color.component.ts">
 </code-example>
 
-The source of truth provides the value and status of the form element at a given point in time. In reactive forms, the form model is the source of truth. In the example above, the form model is the `FormControl` instance.
+Figure 1 shows how, in reactive forms, the form model is the source of truth; it provides the value and status of the form element at any given point in time, through the `[formControl]` directive on the input element.

-With reactive forms, the form model is explicitly defined in the component class. The reactive form directive (in this case, `FormControlDirective`) then links the existing `FormControl` instance to a specific form element in the view using a value accessor (`ControlValueAccessor` instance).
-
 ### Setup in template-driven forms
 
-Here's the same component with an input field for a single control implemented using template-driven forms.
+In template-driven forms, the form model is implicit, rather than explicit. The directive `NgModel` creates and manages a `FormControl` instance for a given form element.
+
+The following component implements the same input field for a single control, using template-driven forms.

+In a template-driven form the source of truth is the template. You do not have direct programmatic access to the `FormControl` instance, as shown in Figure 2.

 {@a data-flow-in-forms}
 
 ## Data flow in forms
 
-When building forms in Angular, it's important to understand how the framework handles data flowing from the user or from programmatic changes. Reactive and template-driven forms follow two different strategies when handling form input. The data flow examples below begin with the favorite color input field example from above, and then show how changes to favorite color are handled in reactive forms compared to template-driven forms.
+When an application contains a form, Angular must keep the view in sync with the component model and the component model in sync with the view.
+As users change values and make selections through the view, the new values must be reflected in the data model.
+Similarly, when the program logic changes values in the data model, those values must be reflected in the view.
+
+Reactive and template-driven forms differ in how they handle data flowing from the user or from programmatic changes.
+The following diagrams illustrate both kinds of data flow for each type of form, using the a favorite-color input field defined above.
 
 ### Data flow in reactive forms
 
-As described above, in reactive forms each form element in the view is directly linked to a form model (`FormControl` instance). Updates from the view to the model and from the model to the view are synchronous and aren't dependent on the UI rendered. The diagrams below use the same favorite color example to demonstrate how data flows when an input field's value is changed from the view and then from the model.

-
-Choosing a strategy begins with understanding the strengths and weaknesses of the options presented. Low-level API and form model access, predictability, mutability, straightforward validation and testing strategies, and scalability are all important considerations in choosing the infrastructure you use to build your forms in Angular. Template-driven forms are similar to patterns in AngularJS, but they have limitations given the criteria of many modern, large-scale Angular apps. Reactive forms minimize these limitations. Reactive forms integrate with reactive patterns already present in other areas of the Angular architecture, and complement those requirements well.

-* Provide visual feedback using special CSS classes that track the state of the controls.
-* Display validation errors to users and enable/disable form controls.
-* Share information across HTML elements using template reference variables.

+## Build a template-driven form
+
+Template-driven forms rely on directives defined in the `FormsModule`.
+
+* The `NgModel` directive reconciles value changes in the attached form element with changes in the data model, allowing you to respond to user input with input validation and error handling.
+
+* The `NgForm` directive creates a top-level `FormGroup` instance and binds it to a `<form>` element to track aggregated form value and validation status.
+As soon as you import `FormsModule`, this directive becomes active by default on all `<form>` tags. You don't need to add a special selector.
+
+* The `NgModelGroup` directive creates and binds a `FormGroup` instance to a DOM element.

+### Step overview
 
-<div class="alert is-helpful">
+In the course of this tutorial, you bind a sample form to data and handle user input using the following steps.
 
-  You can customize the colors and location of the "required" bar with standard CSS.
+1. Build the basic form.
+   * Define a sample data model.
+   * Include required infrastructure such as the `FormsModule`.
+2. Bind form controls to data properties using the `ngModel` directive and two-way data-binding syntax.
+   * Examine how `ngModel` reports control states using CSS classes.
+   * Name controls to make them accessible to `ngModel`.
+3. Track input validity and control status using `ngModel`.
+   * Add custom CSS to provide visual feedback on the status.
+   * Show and hide validation-error messages.
+4. Respond to a native HTML button-click event by adding to the model data.
+5. Handle form submission using the [`ngSubmit`(api/forms/NgForm#properties)] output property of the form.
+   * Disable the **Submit** button until the form is valid.
+   * After submit, swap out the finished form for different content on the page.
 
-</div>
+{@a step1}
 
-You'll build this form in small steps:
+## Build the form
 
-1. Create the `Hero` model class.
-1. Create the component that controls the form.
-1. Create a template with the initial form layout.
-1. Bind data properties to each form control using the `ngModel` two-way data-binding syntax.
-1. Add a `name` attribute to each form-input control.
-1. Add custom CSS to provide visual feedback.
-1. Show and hide validation-error messages.
-1. Handle form submission with *ngSubmit*.
-1. Disable the form’s *Submit* button until the form is valid.
+You can recreate the sample application from the code provided here, or you can examine or download the <live-example></live-example>.
 
-## Setup
+1. The provided sample application creates the `Hero` class which defines the data model reflected in the form.
 
-Create a new project named <code>angular-forms</code>:
+   <code-example path="forms/src/app/hero.ts" header="src/app/hero.ts"></code-example>
 
-<code-example language="sh" class="code-shell">
+2. The form layout and details are defined in the `HeroFormComponent` class.
 
-  ng new angular-forms
+   <code-example path="forms/src/app/hero-form/hero-form.component.ts" header="src/app/hero-form/hero-form.component.ts (v1)" region="v1"></code-example>
 
-</code-example>
+   The component's `selector` value of "app-hero-form" means you can drop this form in a parent
+template using the `<app-hero-form>` tag.
 
-## Create the Hero model class
+3. The following code creates a new hero instance, so that the initial form can show an example hero.
 
-As users enter form data, you'll capture their changes and update an instance of a model.
-You can't lay out the form until you know what the model looks like.
+   <code-example path="forms/src/app/hero-form/hero-form.component.ts" region="SkyDog"></code-example>
 
-A model can be as simple as a "property bag" that holds facts about a thing of application importance.
-That describes well the `Hero` class with its three required fields (`id`, `name`, `power`)
-and one optional field (`alterEgo`).
+   This demo uses dummy data for `model` and `powers`. In a real app, you would inject a data service to get and save real data, or expose these properties as inputs and outputs.
 
-Using the Angular CLI command [`ng generate class`](cli/generate), generate a new class named `Hero`:
+4. The application enables the Forms feature and registers the created form component.
 
-<code-example language="sh" class="code-shell">
+   <code-example path="forms/src/app/app.module.ts" header="src/app/app.module.ts"></code-example>
 
-  ng generate class Hero
+5. The form is displayed in the application layout defined by the root component's template.
 
-</code-example>
+   <code-example path="forms/src/app/app.component.html" header="src/app/app.component.html"></code-example>
 
-With this content:
+   The initial template defines the layout for a form with two form groups and a submit button.
+   The form groups correspond to two properties of the Hero data model, name and alterEgo. Each group has a label and a box for user input.
 
-<code-example path="forms/src/app/hero.ts" header="src/app/hero.ts"></code-example>
+   * The **Name** `<input>` control element has the HTML5 `required` attribute.
+   * The **Alter Ego** `<input>` control element does not because `alterEgo` is optional.
 
-It's an anemic model with few requirements and no behavior. Perfect for the demo.
+   The **Submit** button has some classes on it for styling.
+   At this point, the form  layout is all plain HTML5, with no bindings or directives.
 
-The TypeScript compiler generates a public field for each `public` constructor parameter and
-automatically assigns the parameter’s value to that field when you create heroes.
+6. The sample form uses some style classes from [Twitter Bootstrap](http://getbootstrap.com/css/): `container`, `form-group`, `form-control`, and `btn`.
+   To use these styles, the app's style sheet imports the library.
 
-The `alterEgo` is optional, so the constructor lets you omit it; note the question mark (?) in `alterEgo?`.
+   <code-example path="forms/src/styles.1.css" header="src/styles.css"></code-example>
 
-You can create a new hero like this:
+7. The form makes the hero applicant choose one superpower from a fixed list of agency-approved powers.
+   The predefined list of `powers` is part of the data model, maintained internally in `HeroFormComponent`.
+   The Angular [NgForOf directive](api/common/NgForOf "API reference") iterates over the data values to populate the `<select>` element.
 
-<code-example path="forms/src/app/hero-form/hero-form.component.ts" region="SkyDog"></code-example>

-## Create a form component
-
-An Angular form has two parts: an HTML-based _template_ and a component _class_
-to handle data and user interactions programmatically.
-Begin with the class because it states, in brief, what the hero editor can do.
-
-Using the Angular CLI command [`ng generate component`](cli/generate), generate a new component named `HeroForm`:
-
-<code-example language="sh" class="code-shell">
-
-  ng generate component HeroForm
-
-</code-example>
-
-With this content:
-
-<code-example path="forms/src/app/hero-form/hero-form.component.ts" header="src/app/hero-form/hero-form.component.ts (v1)" region="v1"></code-example>
-
-There’s nothing special about this component, nothing form-specific,
-nothing to distinguish it from any component you've written before.
-
-Understanding this component requires only the Angular concepts covered in previous pages.
-
-* The code imports the Angular core library and the `Hero` model you just created.
-* The `@Component` selector value of "app-hero-form" means you can drop this form in a parent
-template with a `<app-hero-form>` tag.
-* The `templateUrl` property points to a separate file for the template HTML.
-* You defined dummy data for `model` and `powers`, as befits a demo.
-
-Down the road, you can inject a data service to get and save real data
-or perhaps expose these properties as inputs and outputs
-(see [Input and output properties](guide/template-syntax#inputs-outputs) on the
-[Template Syntax](guide/template-syntax) page) for binding to a
-parent component. This is not a concern now and these future changes won't affect the form.
-
-* You added a `diagnostic` property to return a JSON representation of the model.
-It'll help you see what you're doing during development; you've left yourself a cleanup note to discard it later.
-
-## Revise *app.module.ts*
-
-`app.module.ts` defines the application's root module. In it you identify the external modules you'll use in the application
-and declare the components that belong to this module, such as the `HeroFormComponent`.
-
-Because template-driven forms are in their own module, you need to add the `FormsModule` to the array of
-`imports` for the application module before you can use forms.
-
-Update it with the following:
-
-<code-example path="forms/src/app/app.module.ts" header="src/app/app.module.ts"></code-example>
-
-<div class="alert is-helpful">
-
-  There are two changes:
-
-  1. You import `FormsModule`.
-
-  1. You add the `FormsModule` to the list of `imports` defined in the `@NgModule` decorator. This gives the application
-  access to all of the template-driven forms features, including `ngModel`.
-
-</div>
-
-<div class="alert is-important">
-
-  If a component, directive, or pipe belongs to a module in the `imports` array, ​_don't_​ re-declare it in the `declarations` array.
-  If you wrote it and it should belong to this module, ​_do_​ declare it in the `declarations` array.
-
-</div>
-
-## Revise *app.component.html*
-
-`AppComponent` is the application's root component. It will host the new `HeroFormComponent`.
-
-Replace the contents of its template with the following:
-
-<code-example path="forms/src/app/app.component.html" header="src/app/app.component.html"></code-example>
-
-<div class="alert is-helpful">
-
-  There are only two changes.
-  The `template` is simply the new element tag identified by the component's `selector` property.
-  This displays the hero form when the application component is loaded.
-  Don't forget to remove the `name` field from the class body as well.
-
-</div>
-
-## Create an initial HTML form template
-
-Update the template file with the following contents:
-
-<code-example path="forms/src/app/hero-form/hero-form.component.html" region="start" header="src/app/hero-form/hero-form.component.html"></code-example>
-
-The language is simply HTML5. You're presenting two of the `Hero` fields, `name` and `alterEgo`, and
-opening them up for user input in input boxes.
-
-The *Name* `<input>` control has the HTML5 `required` attribute;
-the *Alter Ego* `<input>` control does not because `alterEgo` is optional.
-
-You added a *Submit* button at the bottom with some classes on it for styling.
-
-*You're not using Angular yet*. There are no bindings or extra directives, just layout.
-
-<div class="alert is-helpful">
-
-  In template driven forms, if you've imported `FormsModule`, you don't have to do anything
-  to the `<form>` tag in order to make use of `FormsModule`. Continue on to see how this works.
-
-</div>
-
-The `container`, `form-group`, `form-control`, and `btn` classes
-come from [Twitter Bootstrap](http://getbootstrap.com/css/). These classes are purely cosmetic.
-Bootstrap gives the form a little style.
-
-<div class="callout is-important">
-
-  <header>
-    Angular forms don't require a style library
-  </header>
-
-  Angular makes no use of the `container`, `form-group`, `form-control`, and `btn` classes or
-  the styles of any external library. Angular apps can use any CSS library or none at all.
-
-</div>
-
-To add the stylesheet, open `styles.css` and add the following import line at the top:
-
-<code-example path="forms/src/styles.1.css" header="src/styles.css"></code-example>
-
-## Add powers with _*ngFor_
-
-The hero must choose one superpower from a fixed list of agency-approved powers.
-You maintain that list internally (in `HeroFormComponent`).
-
-You'll add a `select` to the
-form and bind the options to the `powers` list using `ngFor`,
-a technique seen previously in the [Displaying Data](guide/displaying-data) page.
-
-Add the following HTML *immediately below* the *Alter Ego* group:
-
-<code-example path="forms/src/app/hero-form/hero-form.component.html" header="src/app/hero-form/hero-form.component.html (powers)" region="powers"></code-example>
-
-This code repeats the `<option>` tag for each power in the list of powers.
-The `pow` template input variable is a different power in each iteration;
-you display its name using the interpolation syntax.
-
-{@a ngModel}
-
-## Two-way data binding with _ngModel_
-
-Running the app right now would be disappointing.
+If you run the app right now, you see the list of powers in the selection control. The input elements are not yet bound to data values or events, so they are still blank and have no behavior.
 
 <div class="lightbox">
   <img src="generated/images/guide/forms/hero-form-3.png" alt="Early form with no binding">
 </div>
 
+{@a ngModel}
 
-You don't see hero data because you're not binding to the `Hero` yet.
-You know how to do that from earlier pages.
-[Displaying Data](guide/displaying-data) teaches property binding.
-[User Input](guide/user-input) shows how to listen for DOM events with an
-event binding and how to update a component property with the displayed value.
+## Bind input controls to data properties
 
-Now you need to display, listen, and extract at the same time.
+The next step is to bind the input controls to the corresponding `Hero` properties with two-way data binding, so that they respond to user input by updating the data model, and also respond to programmatic changes in the data by updating the display.
 
-You could use the techniques you already know, but
-instead you'll use the new `[(ngModel)]` syntax, which
-makes binding the form to the model easy.
+The `ngModel` directive declared in the `FormsModule` lets you bind controls in your template-driven form to properties in your data model.
+When you include the directive using the  syntax for two-way data binding, `[(ngModel)]`, Angular can track the value and user interaction of the control and keep the view synced with the model.
 
-Find the `<input>` tag for *Name* and update it like this:
+1. Edit the template file `hero-form.component.html`.
+
+2. Find the `<input>` tag next to the **Name** label.
+
+3. Add the `ngModel` directive, using two-way data binding syntax `[(ngModel)]="..."`.
 
 <code-example path="forms/src/app/hero-form/hero-form.component.html" header="src/app/hero-form/hero-form.component.html (excerpt)" region="ngModelName-1"></code-example>
 
 <div class="alert is-helpful">
 
-  You added a diagnostic interpolation after the input tag
-  so you can see what you're doing.
-  You left yourself a note to throw it away when you're done.
+This example has a temporary diagnostic interpolation after each input tag, `{{model.name}}`, to show the current data value of the corresponding property.
+The note reminds you to remove the diagnostic lines when you have finished observing the two-way data binding at work.

-Focus on the binding syntax: `[(ngModel)]="..."`.
+{@a ngForm}
 
-You need one more addition to display the data. Declare
-a template variable for the form. Update the `<form>` tag with

-<code-example path="forms/src/app/hero-form/hero-form.component.html" header="src/app/hero-form/hero-form.component.html (excerpt)" region="template-variable"></code-example>
+When you imported the `FormsModule` in your component, Angular automatically created and attached an [NgForm](api/forms/NgForm "API reference for NgForm") directive to the `<form>` tag in the template (because `NgForm` has the selector `form` that matches `<form>` elements).
 
-The variable `heroForm` is now a reference to the `NgForm` directive that governs the form as a whole.
+To get access to the `NgForm` and the overall form status, declare a [template reference variable](guide/template-syntax#template-reference-variables-var).

-  What `NgForm` directive?
-  You didn't add an [NgForm](api/forms/NgForm) directive.
+   The `heroForm` template variable  is now a reference to the `NgForm` directive instance that governs the form as a whole.
 
-  Angular did. Angular automatically creates and attaches an `NgForm` directive to the `<form>` tag.
+3. Run the app.
 
-  The `NgForm` directive supplements the `form` element with additional features.
-  It holds the controls you created for the elements with an `ngModel` directive
-  and `name` attribute, and monitors their properties, including their validity.
-  It also has its own `valid` property which is true only *if every contained
-  control* is valid.
+4. Start typing in the **Name** input box.
 
-</div>
+  As you add and delete characters, you can see them appear and disappear from the data model.
+  For example:
 
-If you ran the app now and started typing in the *Name* input box,
-adding and deleting characters, you'd see them appear and disappear
-from the interpolated text.
-At some point it might look like this:

+  The diagnostic line that shows interpolated values demonstrates that values are really flowing from the input box to the model and back again.
 
-The diagnostic is evidence that values really are flowing from the input box to the model and
-back again.
+### Naming control elements
 
-<div class="alert is-helpful">
+When you use `[(ngModel)]` on an element, you must define a `name` attribute for that element.
+Angular uses the assigned name to register the element with the `NgForm` directive attached to the parent `<form>` element.
 
-  That's *two-way data binding*.
-  For more information, see
-  [Two-way binding with NgModel](guide/template-syntax#ngModel) on the
-  the [Template Syntax](guide/template-syntax) page.
+The example added a `name` attribute to the `<input>` element and set it to "name",
+which makes sense for the hero's name.
+Any unique value will do, but using a descriptive name is helpful.
 
-</div>
+1. Add similar `[(ngModel)]` bindings and `name` attributes to **Alter Ego** and **Hero Power**.
 
-Notice that you also added a `name` attribute to the `<input>` tag and set it to "name",
-which makes sense for the hero's name. Any unique value will do, but using a descriptive name is helpful.

-<div class="alert is-helpful">
+3. To confirm that two-way data binding works for the entire hero model, add a new binding at the top to the component's `diagnostic` property.
 
-  Internally, Angular creates `FormControl` instances and
-  registers them with an `NgForm` directive that Angular attached to the `<form>` tag.
-  Each `FormControl` is registered under the name you assigned to the `name` attribute.

-* The "*is required*" message in a nearby `<div>`, which you'll display only if the control is invalid.
+To define and show an error message when appropriate, take the following steps.
 
-Here's an example of an error message added to the _name_ input box:
+1. Extend the `<input>` tag with a template reference variable that you can use to access the input box's Angular control from within the template. In the example, the variable is `#name="ngModel"`.
 
-<code-example path="forms/src/app/hero-form/hero-form.component.html" header="src/app/hero-form/hero-form.component.html (excerpt)" region="name-with-error-msg"></code-example>
+   <div class="alert is-helpful">
 
-You need a template reference variable to access the input box's Angular control from within the template.
-Here you created a variable called `name` and gave it the value "ngModel".
+     The template reference variable (`#name`) is set to `"ngModel"` because that is the value of the [`NgModel.exportAs`](api/core/Directive#exportAs) property. This property tells Angular how to link a reference variable to a directive.
 
-<div class="alert is-helpful">
+   </div>
 
-  Why "ngModel"?
-  A directive's [exportAs](api/core/Directive) property
-  tells Angular how to link the reference variable to the directive.
-  You set `name` to `ngModel` because the `ngModel` directive's `exportAs` property happens to be "ngModel".
-
-</div>
-
-You control visibility of the name error message by binding properties of the `name`
+2. Add a `<div>` that contains a suitable error message.
+3. Show or hide the error message by binding properties of the `name`
 control to the message `<div>` element's `hidden` property.

-In this example, you hide the message when the control is valid or pristine;
-"pristine" means the user hasn't changed the value since it was displayed in this form.
+4. Add a conditional error message to the _name_ input box, as in the following example.
 
-This user experience is the developer's choice. Some developers want the message to display at all times.
+   <code-example path="forms/src/app/hero-form/hero-form.component.html" header="src/app/hero-form/hero-form.component.html (excerpt)" region="name-with-error-msg"></code-example>
+
+<div class="callout is-helpful">
+
+<header>Illustrating the "pristine" state</header>
+
+In this example, you hide the message when the control is either valid or *pristine*.
+Pristine means the user hasn't changed the value since it was displayed in this form.
 If you ignore the `pristine` state, you would hide the message only when the value is valid.
 If you arrive in this component with a new (blank) hero or an invalid hero,
 you'll see the error message immediately, before you've done anything.
 
-Some developers want the message to display only when the user makes an invalid change.
-Hiding the message while the control is "pristine" achieves that goal.
-You'll see the significance of this choice when you add a new hero to the form.
+You might want the message to display only when the user makes an invalid change.
+Hiding the message while the control is in the `pristine` state achieves that goal.
+You'll see the significance of this choice when you add a new hero to the form in the next step.
 
-The hero *Alter Ego* is optional so you can leave that be.

-Hero *Power* selection is required.
-You can add the same kind of error handling to the `<select>` if you want,
-but it's not imperative because the selection box already constrains the
-power to valid values.
+## Add a new hero
 
-Now you'll add a new hero in this form.
-Place a *New Hero* button at the bottom of the form and bind its click event to a `newHero` component method.
+This exercise shows how you can respond to a native HTML button-click event by adding to the model data.
+To let form users add a new hero, you will add a **New Hero** button that responds to a click event.
 
-<code-example path="forms/src/app/hero-form/hero-form.component.html" region="new-hero-button-no-reset" header="src/app/hero-form/hero-form.component.html (New Hero button)"></code-example>
+1. In the template, place a "New Hero" `<button>` element at the bottom of the form.
+2. In the component file, add the hero-creation method to the hero data model.
 
-<code-example path="forms/src/app/hero-form/hero-form.component.ts" region="new-hero" header="src/app/hero-form/hero-form.component.ts (New Hero method)"></code-example>
+   <code-example path="forms/src/app/hero-form/hero-form.component.ts" region="new-hero" header="src/app/hero-form/hero-form.component.ts (New Hero method)"></code-example>
 
-Run the application again, click the *New Hero* button, and the form clears.
-The *required* bars to the left of the input box are red, indicating invalid `name` and `power` properties.
-That's understandable as these are required fields.
-The error messages are hidden because the form is pristine; you haven't changed anything yet.
+3. Bind the button's click event to a hero-creation method, `newHero()`.
 
-Enter a name and click *New Hero* again.
-The app displays a _Name is required_ error message.
-You don't want error messages when you create a new (empty) hero.
-Why are you getting one now?

-Inspecting the element in the browser tools reveals that the *name* input box is _no longer pristine_.
-The form remembers that you entered a name before clicking *New Hero*.
-Replacing the hero object *did not restore the pristine state* of the form controls.
+4. Run the application again and click the **New Hero** button.
 
-You have to clear all of the flags imperatively, which you can do
-by calling the form's `reset()` method after calling the `newHero()` method.
+   The form clears, and the *required* bars to the left of the input box are red, indicating invalid `name` and `power` properties.
+   Notice that the error messages are hidden. This is because the form is pristine; you haven't changed anything yet.

+5. Enter a name and click **New Hero** again.
 
-Now clicking "New Hero" resets both the form and its control flags.
+   Now the app displays a _Name is required_ error message, because the input box is no longer pristine.
+   The form remembers that you entered a name before clicking **New Hero**.
+
+6. To restore the pristine state of the form controls, clear all of the flags imperatively by calling the form's `reset()` method after calling the `newHero()` method.

-You'd already defined a template reference variable,
-`#heroForm`, and initialized it with the value "ngForm".
-Now, use that variable to access the form with the Submit button.
+2. Use the template reference variable, `#heroForm` to access the form that contains the **Submit** button and create an event binding.
+You will bind the form property that indicates its overall validity to the **Submit** button's `disabled` property.

-Now if you delete the Name, you violate the "required" rule, which
-is duly noted in the error message.
-The *Submit* button is also disabled.
+4. Delete the **Name** value. This violates the "required" rule, so it displays the error message&emdash;and notice that it also disables the **Submit** button.
 
-Not impressed?  Think about it for a moment. What would you have to do to
-wire the button's enable/disabled state to the form's validity without Angular's help?
 
-For you, it was as simple as this:
+   You didn't have to explicitly wire the button's enabled state to the form's validity.
+   The `FormsModule` did this automatically when you defined a template reference variable on the enhanced form element, then referred to that variable in the button control.

+# Browser configuration and versioning for testing of Angular
+
+Within the Angular monorepo, we use Chrome to perform most of the local testing, and rely on Sauce Labs and BrowserStack to do cross-browser testing on our CI.
+
+The version of Chrome used in tests within this monorepo is configured and controlled via `rules_webtesting` and `puppeteer`. We manually keep the configuration of these two tools in sync to create a consistent testing environment across unit, e2e, and integration tests.
+
+## rules_webtesting
+
+Bazel `karma_web_test_suite` and `protractor_web_test_suite` targets will use Chromium provisioned by rules_webtesting. The version of chrome used is specified in the `dev-infra/browsers/browser_repositories.bzl` file. The process of updating the Chrome version in that file consists of several steps:
+
+1) Visit https://chromium.woolyss.com/ and note the version (commit position) of the latest stable version.
+
+    For example, "Google Chrome 83.0.4103.97 (756066) • Wednesday, 3 Jun 2020". Alternately, you can look in https://omahaproxy.appspot.com/.
+
+1) Find the closest commit position number available for each platform in chromium-browser-snapshots:
+ https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html
+
+   For example,
+
+   * https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Linux_x64/756066/
+   * https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Mac/756053/
+   * https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Win/756065/
+
+   You can download the Chromium for your local platform and double check that the --version matches up with
+   what you expect.
+
+   For example,
+
+``` bash
+$ ~/Downloads/chrome-mac/Chromium.app/Contents/MacOS/Chromium --version
+Chromium 83.0.4103.0
+```
+
+1) Update the chrome & chrome driver build numbers in `dev-infra/browsers/browser_repositories.bzl` and run either run `bazel query @org_chromium_chromium_amd64//...` to prompt Bazel to calculate the new sha256 for each platform binary or determine the new sha256 values manually.
+
+    For example, with curl & shasum
+
+``` bash
+curl https://commondatastorage.googleapis.com/chromium-browser-snapshots/Linux_x64/756066/chrome-linux.zip | shasum -a 256
+```
+
+## puppeteer
+
+Visit https://github.com/puppeteer/puppeteer/blob/master/docs/api.md to determine which version of puppeteer corresponds to the version of Chrome desired. Then update `scripts/puppeteer-chrome-versions.js` and all of the puppeteer versions throughout the repo,
+
+* `package.json`
+* `aio/package.json`
+* `aio/tools/examples/shared/package.json`
+
+and their corresponding `yarn.lock` files.
