+# Contributing
+
+## Getting Started
+
+1. Fork & Clone this repo
+1. [`nvm install`](https://github.com/nvm-sh/nvm)
+1. [`nvm use`](https://github.com/nvm-sh/nvm)
+1. `yarn install`
+
+## Documentation Development
+
+1. Run the documentation via `yarn docs`
+1. Visit <http://localhost:3000/>
+1. Create/Update content based on the URL.
+
+   For example, the content for
+   http://localhost:3000/components/authenticator is located at [`docs/src/content/components/authenticator/index.mdx`](docs/src/content/components/authenticator/index.mdx)
+
+Internally, this content is served by a single, Next.js [optional catch all route](https://nextjs.org/docs/routing/dynamic-routes#optional-catch-all-routes):
+[`docs/src/pages/[[...slugs]].tsx`](docs/src/pages/[[...slugs]].tsx).
+
+## React Development
+
+1. `yarn docs` to run the development server
+1. Create or Update an example at [`docs/src/pages/component/authenticator/examples/...`](docs/src/pages/component/authenticator/examples)
+
+   ```js
+   // .../authenticator/examples/sign-in.ts
+   import { Authenticator } from "aws-amplify-react";
+   import { Amplify } from "aws-amplify";
+   import "@aws-amplify/ui/dist/style.css";
+
+   // **You will need to provide this file yourself**
+   import awsExports from "./aws-exports";
+
+   Amplify.configure(awsExports);
+
+   export default function Example() {
+     return <Authenticator />;
+   }
+   ```
+
+1. Visit your example (.e.g. <http://localhost:3000/docs/src/pages/component/authenticator/examples/sign-in>)
+1. Make changes to [`@aws-amplify/ui-react`](packages/react) & save.
+
+   Next.js should automatically hot-reload your changes in the example.
+
+### Documentation & Testing
+
+1. Create or Update a `${feature}.feature` file (using [Gherkin](https://cucumber.io/docs/gherkin/reference/)) describing the behavior in [`packages/e2e/cypress/tests/acceptance/${slug}`](packages/e2e/cypress/tests/acceptance).
+
+   ```gherkin
+   Feature: My new feature
+
+     Documentation-friendly description of this feature, why it exists, & how to use it.
+
+     Scenario: Example scenario using this feature
+       Given some "STARTING_POINT"
+       When I DO "SOMETHING"
+       And I DO SOMETHING "ELSE"
+       Then I see "THE DESIRED BEHAVIOR"
+   ```
+
+1. Create or Update the accompanying `${slug}.feature` tests (e.g. `packages/e2e/cypress/tests/acceptance/${slug}/${feature}/${feature}.ts`
+1. Run `yarn workspace e2e dev` to load Cypress
+1. Click on your updated `${feature}.feature` file to validate your changes
