+
+## Gatsby.js Starters
+
+Running `gatsby new` installs the default Gatsby starter. There are many other official and community starters you can use to kickstart building your Gatsby site.
+
+### Default Starter
+
+Kick off your project with this default boilerplate. This barebones starter ships with the main Gatsby configuration files you might need.
+
+#### Quick start
+
+1.  **Install the Gatsby CLI.**
+
+    The Gatsby CLI helps you create new sites using Gatsby starters (like this one!)
+
+    ```sh
+    # install the Gatsby CLI globally
+    npm install -g gatsby-cli
+    ```
+
+2.  **Create a Gatsby site.**
+
+    Use the Gatsby CLI to create a new site, specifying the default starter.
+
+    ```sh
+    # create a new Gatsby site using the default starter
+    gatsby new website
+    ```
+
+3.  **Start developing.**
+
+    Navigate into your new site’s directory and start it up.
+
+    ```sh
+    cd website/
+    gatsby develop
+    ```
+
+4.  **Open the source code and start editing!**
+
+    Your site is now running at `http://localhost:8000`
+
+    *Note: You'll also see a second link: `http://localhost:8000/___graphql`. This is a tool you can use to experiment with querying your data. Learn more about using this tool in the [Gatsby tutorial](https://www.gatsbyjs.org/tutorial/part-five/#introducing-graphiql).*
+    
+    Open the `website` directory in your code editor of choice and edit `src/pages/index.js`. Save your changes and the browser will update in real time!
+
+### Other Starters
+
+Other starters offer more options and features but with depending on your working knowledge, working on these starters might not be pretty straightforward for beginners. [Check other official and community starters here](https://www.gatsbyjs.org/starters/).
