 With the spec file foundation, the custom element can now be created and applied to the mock DOM environment. To do this, we use the Web Test Runner (WTR) framework which provides the scaffolding to test Web Componets in a browser environment.
 
-The WTR and the full setup is covered in greater detail within [the GreenwoodJS test runner docs](https://super-tapioca-5987ce.netlify.app/guides/ecosystem/web-test-runner/). In an attempt to not duplicate those docs, an outline has been provided here, but please refer to those docs for a full user guide.

    Install dependencies and configure WTR. This project has that covered already! ✅ (Let's chat if there becomes a need to reconfigure the current setup.)

+#### _Content as Data_ Stories
+
+When a component requires a `fetch` request for data, the story will need to mock this request before being able to render within the Storybook. 
+
+To mock `fetch`, create a `parameter` within the story export object named `fetchMock`. This object contains a `mocks` array with a `matcher` for the localhost network request URL. The `matcher.response` object represents the mocked data to use with the story.
+
+Checkout [the `blog-posts-list.stories.js` story](https://github.com/ProjectEvergreen/www.greenwoodjs.dev/blob/main/src/components/blog-posts-list/blog-posts-list.stories.js) as an example.
+
+```js
+import "./my-custom-element.js";
+import pages from "../../stories/mocks/graph.json";
+
+export default {
+  title: "Components/My Custom Element",
+  parameters: {
+    // ...other parameters, if necessary...
+    fetchMock: {
+      mocks: [
+        {
+          matcher: {
+            url: "http://localhost:1985/graph.json",
+            response: {

 ## Hosting and Deployment
 
 This project is hosted on Netlify and automatically deploys on each merge into main. Release branches will be curated over the course of a Greenwood release cycle and then merged at the time the new Greenwood release is published to NPM.
