+
+### In this guide
+
+- [Install the library and dependencies](#install-the-library-and-dependencies)
+- [Create required files](#create-required-files)
+
+### Install the library and dependencies
+
+1. Install the library:
+```bash
+npm install --save https://github.com/usds/us-forms-system.git
+```
+
+2. Install peer dependencies:
+```bash
+npm install --save-dev @department-of-veterans-affairs/formation
+npm install --save-dev uswds@^1.6.3
+npm install --save-dev react@^15.5.4
+npm install --save-dev react-dom@^15.6.2
+```
+
+### Create required files
+
+To enable your form, create the following files. For an example of these files, see the [us-forms-system-starter-app repository](https://github.com/usds/us-forms-system-starter-app).
+
+- A [form config file](https://github.com/usds/us-forms-system-starter-app/blob/master/js/config/form.js). For more information, see "Creating a form config file."
+- An entry [app.js](https://github.com/usds/us-forms-system-starter-app/blob/master/app.js) file.
+- A [React component](https://github.com/usds/us-forms-system-starter-app/blob/master/js/components/Form.jsx) to render the top-level us-forms-system component.
+- A [routes file](https://github.com/usds/us-forms-system-starter-app/blob/master/js/routes.jsx) that loads `createRoutes` from us-forms-system. This automatically creates the routes from the form config file.
+- A [reducers file](https://github.com/usds/us-forms-system-starter-app/blob/master/js/reducers.js) that loads `createSchemaFormReducer` from us-forms-system. This creates the app's reducer functions.
