 # example: component-tests
 
-This example is built based on the instructions from the [Cypress documentation](https://docs.cypress.io/)
-[React Quickstart](https://docs.cypress.io/guides/component-testing/react/quickstart). It uses [Vite](https://vitejs.dev/) to create the app.
+This example was built as follows:
+
+1. [Vite > Getting Started](https://vitejs.dev/guide/) instructions with the [react](https://vite.new/react) template were used to create the app
+    ```bash
+    npm create vite@latest component-tests -- --template react
+    ```
+    The linting `npm` modules and linting script have been removed, since this is out-of-scope for the example.
+1. The Cypress documentation instructions from [Component Testing > Getting Started](https://on.cypress.io/guides/component-testing/getting-started) were followed to set up component testing, including copying
+
+    - `<Stepper />` component: [react/my-awesome-app/src/components/Stepper.jsx](https://github.com/cypress-io/component-testing-quickstart-apps/blob/main/react/my-awesome-app/src/components/Stepper.jsx)
+
+    from the [Cypress Component Testing Quickstart Apps](https://github.com/cypress-io/component-testing-quickstart-apps) repo to this repo's `examples/component-tests/src/components/` sub-directory.
+1. The script `"test": "cypress run --component"` was added to `package.json`.
+## Execution
+
+Execute the following to change to this directory:
+
+```bash
+cd examples/component-tests
+```
+
+Install dependencies with:
+
+```bash
+npm ci
+```
+
+Run Cypress component testing with:
+
+```bash
+npm test
+```
