 # U.S. Forms System
 
+The US Forms System is an open source library and set of guiding principles for building complex web-based forms using [React](https://reactjs.org), the [JSON Schema standard](http://json-schema.org/), and the [US Web Design System](https://designsystem.digital.gov/).
+
 ***THIS IS A WORK IN PROGRESS.***
 
-Modelled after the [US Web Design System](https://designsystem.digital.gov/), this project creates an open source code library and set of guiding principles for building complex web-based forms significantly faster than existing methods, using best practices in user experience and data collection, validation, and transmission.
+### About this project
+
+Inspired by Mozilla's [react-jsonschema-form](https://github.com/mozilla-services/react-jsonschema-form) library, the US Forms System is specifically intended for consistently styled governmental web-based forms. This library enables you to describe form fields in a JSON Schema configuration file, which then renders the backing React components necessary to build your form. You'll build forms significantly faster than existing methods, and benefit from the US Web Design System's best practices in user experience and data collection, validation, and transmission.
+
+### Using the library
+
+For information about setting up and using the US Forms System, see the *[US Forms System Documentation](./docs/README.md)*.
+
+Additionally, the [US Forms System Starter App](https://github.com/usds/us-forms-system-starter-app) provides the basic files and configuration needed to get started building a form using the US Forms System.
+
+### Contributing to this project:
+
+Please read our [Code of Conduct](https://github.com/usds/us-forms-system/blob/master/CODE_OF_CONDUCT.md) and [CONTRIBUTING.md](https://github.com/usds/us-forms-system/blob/master/CONTRIBUTING.md) for more details.

-This library enables you to build web-based forms using [React](https://reactjs.org) and the [JSON Schema standard](http://json-schema.org/). Instead of building and configuring your React components from scratch, use this library and guidance to describe the form fields in a JSON Schema configuration file, which will then render the backing React components necessary to build your form.
+#### Contact the project team:
 
-Originally inspired by Mozilla's [react-jsonschema-form](https://github.com/mozilla-services/react-jsonschema-form) library, we've created a version specific build web-based forms for government, styled using the [U.S. Web Design System](https://designsystem.digital.gov/) for a consistent look and feel across government.
+If you want to directly contact the project team, you can send your questions to [email protected].gov.

+### [Common definitions](common-definitions.md)
 
-There are many common fields and widgets you can use to build forms. There are common types of definitions: `schema`/`uiSchema` objects and functions that return `schema`/`uiSchema` objects.
+Definitions are pieces of the form config that can be dropped in to represent specific types of questions. Most often used in `uiSchema`, definitions include features such as label text, validation functions, error messages, and rules for which widget to render.
 
 ### [Common patterns for building forms](common-patterns-for-building-forms.md)
 
 Some forms require custom validation, styles, or conditional information based on user input. Use these patterns to address those needs.

+
+The US Forms System lets you build web-based forms using the JSON Schema standard for form data and React for the form UI. The form data and UI are represented by `schema` and `uiSchema` objects, respectively, which are included in the form configuration file.

+  - [Configuring `uiSchema` using US Form System options](#configuring-uischema-using-us-forms-system-options)
+
+### Understanding the `schema` object
+
+The JSON Schema standard describes the allowed shape of JSON objects. Using a `schema` object, a JSON schema provides information about structured JSON data. For more information about the JSON Schema Standard, see [Understanding JSON Schema](https://spacetelescope.github.io/understanding-json-schema/).
+
+For JSON Schema validator libraries, the US Forms System uses [ajv](https://www.npmjs.com/package/ajv) for unit tests and [jsonschema](https://www.npmjs.com/package/jsonschema) in the us-forms-system code.
+
+##### Describing object fields and arrays
+
+This example describes a JSON document that is an object with one property called `myField`, which is a number, meaning `{ myField: 2 }` would be valid:
+
+```
+{
+  type: 'object',
+  properties: {
+    myField: {
+      type: 'number'
+    }
+  }
+}
+```
+
+However, `{}` is also valid. To require a property in an object, use the `required` property, which takes an array of property names passed as strings. As in this example, `required` is always on the object that contains the field, not the field itself:
+
+```
+{
+  type: 'object',
+  required: ['myField'],
+  properties: {
+    myField: {
+      type: 'number'
+    }
+  }
+}
+```
+
+Arrays work similarly to objects. This example describes an array of boolean values: `[true, false, true]`. Items can be an object schema or any other type of schema as well:
+
+```
+{
+  type: 'array',
+  items: {
+    type: 'boolean'
+  }
+}
+```
+
+### Understanding the `uiSchema` object
+
+The `uiSchema` object was introduced by [react-jsonschema-form](https://github.com/mozilla-services/react-jsonschema-form#react-jsonschema-form), or *rjsf*, as a means of describing how a form page should be rendered from a `schema`. To generate a form, react-jsonschema-form steps through the schema depth and renders different React components based on the type of data each property in the schema represents. In the US Forms System library, `uiSchema` follows the format described in the [react-jsonschema-form documentation](https://github.com/mozilla-services/react-jsonschema-form#the-uischema-object), with some custom us-forms-system additions. The `schema` and `uiSchema` objects should have a similar structure, with the same fields organized in the same way with these exceptions:
+
+- `uiSchema` doesn't need to contain all the fields found in the `schema` object.
+- `uiSchema` doesn't need a `properties` object for sub-fields.
+
+For example, given this schema:
+
+```js
+{
+  type: 'object',
+  properties: {
+    field1: {
+      type: 'string'
+    }
+  }
+}
+```
+
+The matching `uiSchema` would be:
+
+```js
+{
+  'ui:title': 'My form',
+  field1: {
+    'ui:title': 'My field'
+  }
+}
+```
+
+For array fields, you must specify an `items` object that contains the fields for each row in the array in the `uiSchema` object:
+
+```js
+{
+  'ui:title': 'My form',
+  toursOfDuty: {
+    items: {
+      branchName: {
+        'ui:title': 'Branch'
+      }
+    }
+  }
+}
+```
+
+##### Configuring `uiSchema` using rjsf options
+
+If you're not already familiar with the rjsf uiSchema options, see the [rjsf library documentation](https://github.com/mozilla-services/react-jsonschema-form#the-uischema-object). Some commonly used options include:
+
+- [ui:order](https://github.com/mozilla-services/react-jsonschema-form#object-fields-ordering): An array of field names in the order in which they should appear.
+- [ui:widget](https://github.com/mozilla-services/react-jsonschema-form#alternative-widgets): The name of an alternative widget to use for the field, for example, a custom widget called `yesNo`.
+- [ui:field](https://github.com/mozilla-services/react-jsonschema-form#custom-field-components): The name of a custom field.
+- [classNames](https://github.com/mozilla-services/react-jsonschema-form#custom-css-class-names): The class names to put on the component.
+
+##### Configuring `uiSchema` using US Forms System options
+
+The us-forms-system code includes additional `uiSchema` functionality not found in the rjsf library.
+
+```js
+{
+  // Used instead of the `title` property in the JSON Schema.
+  'ui:title': '',
+  // It can also be a component, which passes the current form data as a property.
+  'ui:title': ({ formData }) => <legend>{`A ${formData.thing} title`}</legend>,
+
+  // Used instead of the `description` property in the JSON Schema. This can be a string
+  // or a React component, and is normally used on object fields in the schema to provide
+  // description text or HTML before a block of fields.
+  'ui:description': '' || DescriptionComponent,
+
+  // Customizes the field or widget you're using.
+  'ui:field': '' || FieldComponent,
+  'ui:widget': '' || WidgetComponent,
+
+  // Renders string fields on the review page. Always used when you specify a custom widget
+  // component. Can also be used with regular widgets.
+  'ui:reviewWidget': WidgetComponent,
+
+  // Provides a function to make a field conditionally required. The data in the whole form,
+  // with no page breaks, is the only parameter. Don't make a field required in the JSON
+  // schema and in addition to using `ui:required` on that field. The index argument is
+  // provided if you use `ui:required` on data inside an array.
+  'ui:required': function (formData, index) {
+    return true || false;
+  },
+
+  // An array of validation functions or objects that you can use to add validation that's
+  // not possible through JSON Schema. See below for the properties passed to the validation
+  // functions and how to use them.
+  'ui:validations': [
+    /**
+     * Note the difference between the three data parameters:
+     *
+     * @param {any} fieldData The data for the current field being validated
+     * @param {object} formData The data for all the fields in every page
+     */
+    function (errors, fieldData, formData, fieldSchema, errorMessages) {
+      errors.addError('My error');
+    },
+    {
+      validator: (errors, fieldData, formData, fieldSchema, errorMessages, options) => {
+        errors.addError('My other error');
+      },
+      options: {}
+    }
+  ],
+
+  // An object with field-specific error messages. Structured by error name (from JSON Schema
+  // error types). This is passed to custom validations in `ui:validations` in order to allow
+  // configurable error messages in a validator.
+  'ui:errorMessages': {
+    'pattern': 'Please provide a value in the right format'
+  },
+  'ui:options': {
+
+    // An map of enum values to labels that are shown by the select and radio widgets.
+    labels: {
+      chapter30: 'A readable description (Chapter 30)'
+    },
+
+    // A map of values to a component, text, or JSX

+    },
+
+    // A string of class names that are added to the widget for the current field.

+    viewField: RowViewComponent,
+
+    // To show a field only when another field is true, set this option to the property name.
+    // It wraps the fields with an ExpandingGroup component using the `expandUnder` field as
+    // the first question.
+    expandUnder: '',
+
+    // To match to a specific value, use the `expandUnderCondition` option to specify the
+    // value that the `expandUnder` field's data should equal.
+    expandUnderCondition: 'someValue',
+    // `expandUnderCondition` can also be a function that receives the data from the
+    // `expandUnder` field as an argument.
+    expandUnderCondition: (field) => field === 'someValue' || field === 'someOtherValue',
+
+    // When using the expandUnder option, you can set `expandUnderClassNames` on the field
+    // specified by `expandUnder` and it will add classes to the `div` that wraps all of the
+    // fields when they're expanded. See cookbook for an example use case.
+    expandUnderClassNames: '',
+
+    // Hides the specified field on the review page.
+    hideOnReview: true || false,
+
+    // Hides the specified field on the review page when the field value is `false`.
+    hideOnReviewIfFalse: true || false
+
+    // A function that conditionally hides fields in the form. `hideIf` provides the `index`
+    // argument when you use `ui:required` on data inside an array.
+    hideIf: function (formData, index) {
+      return true || false;
+    }
+
+    // A function that conditionally replaces the current field's schema. `updateSchema`
+    // provides the `index` argument when you use `ui:required` on data inside an array.
+    updateSchema: function (formData, schema, uiSchema, index, pathToCurrentData) {
