+
+## The problem
+
+You are working with Twig in a styleguide-driven-development process. You are writing isolated components
+that consist of css, twig and Javascript.
+You want to be able to test your Javascript in relation to your twig file with maximum isolation.
+
+## This solution
+
+The `Twig Testing Library` is a very lightweight solution based on [Twig JS](https://github.com/twigjs/twig.js) for
+testing Twig-based components. It is heavily influenced by similar libraries such as [React Testing Library](https://testing-library.com/docs/react-testing-library/intro).
+It provides light utility functions on top of `Twig JS` and [Dom testing library](https://testing-library.com/docs/dom-testing-library/intro)
+in a way that encourages better testing practices. 
+
+## Installation
+
+This module is distributed via [npm][npm] which is bundled with [node][node] and
+should be installed as one of your project's `devDependencies`:
+
+```
+npm install --save-dev twig-testing-library
+```
+
+You may also be interested in installing `@testing-library/jest-dom` so you can
+use [the custom jest matchers](https://github.com/testing-library/jest-dom).
+
+## Examples
+
+### Basic Example
+
+```javascript
+// accordion.js
+
+class Accordion {
+  constructor(obj) {
+    this.accordion = obj;
+    this.summary = obj.querySelector('.accordion__title');
+  }
+
+  init() {
+    const open = this.accordion.hasAttribute('open');
+    if (open) {
+      this.accordion.classList.add('accordion--open');
+    }
+    this.summary.addEventListener('focus', () => {
+      this.handleFocus();
+    });
+    this.summary.addEventListener('blur', () => {
+      this.handleBlur();
+    });
+    this.summary.addEventListener('click', () => {
+      this.handleClick();
+    });
+  }
+
+  handleFocus() {
+    // Focus class for styling.
+    this.accordion.classList.add('has-focus');
+  }
+
+  handleBlur() {
+    // Focus class for styling.
+    this.accordion.classList.remove('has-focus');
+  }
+
+  handleClick() {
+    const open = this.accordion.classList.contains('accordion--open');
+    this.summary.setAttribute('aria-expanded', !open);
+    this.summary.setAttribute('aria-pressed', !open);
+    this.accordion.classList.toggle('accordion--open');
+  }
+}
+
+export default { Accordion };
+```
+
+```javascript
+// __tests__/accordion.js
+import { render, fireEvent } from 'twig-testing-library'
+
+describe('Accordion toggling', () => {
+  it('Can be rendered open, and then collapsed on click', async () => {
+    // Rendering is async, so you need to use await.
+    const { container, getByText } = await render(
+    // Path to twig template.
+    'accordion.twig',
+    // Template variables/context. 
+    {
+      title: 'Accordion title',
+      open: true,
+    }, 
+    // Namespace support
+    {
+      'my_namespace': './some/path'
+    });
+    const accordionElement = container.querySelector('.accordion');
+    const accordion = new Accordion.Accordion(accordionElement);
+    accordion.init();
+    // Snapshot support via jest.
+    expect(accordionElement).toMatchSnapshot('Initial render');
+    expect(accordionElement.classList.contains('accordion--open')).toBe(true);
+    fireEvent.click(getByText('Accordion title'));
+    expect(accordionElement).toMatchSnapshot('First collapse');
+    expect(accordionElement.classList.contains('accordion--open')).toBe(false);
+  })
+})
+```
+
+### More Examples
+
+- Refer to the [Dom testing library docs](https://testing-library.com/docs/dom-testing-library/example-intro), we're really just adding the ability to render twig templates on top of that.
+
+## Issues
+
+### 🐛 Bugs
