+# Express Bootstrap
+
+This project is a boilerplate for Node.js/Express applications. It also comes included with Jest, and Supertest for end-to-end testing.
+
+## Getting started
+
+Ensure your Visual Studio Code application is up to date, and that you have the [ESLint extension](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint) installed and enabled.
+
+Replace `your-project-folder-name` with the folder name you wish to create for your project and run the below inside your `Projects` folder.
+
+```bash
+git clone [email protected]:MCRcodes/express-bootstrap.git your-project-folder-name
+cd your-project-folder-name
+npm install
+npm start
+```
+
+Visit [http://localhost:3000/] in your browser and you should see `Hello world!`. You can dive in and start coding your own routes in `src/app.js`.
+
+## Running tests
+
+You can run tests with the `npm test` command.
+
+## Remember: READMEs are important!
+
+When you're finished, be sure to rewrite this one so it's more specific to your project.
