+  Gatsby's blog starter
+</h1>
+
+Kick off your project with this blog boilerplate. This starter ships with the main Gatsby configuration files you might need to get up and running blazing fast with the blazing fast app generator for React.
+
+_Have another more specific idea? You may want to check out our vibrant collection of [official and community-created starters](https://www.gatsbyjs.com/docs/gatsby-starters/)._
+
+## 🚀 Quick start
+
+1.  **Create a Gatsby site.**
+
+    Use the Gatsby CLI ([install instructions](https://www.gatsbyjs.com/docs/tutorial/part-0/#gatsby-cli)) to create a new site, specifying the blog starter.
+
+    ```shell
+    # create a new Gatsby site using the blog starter
+    gatsby new my-blog-starter https://github.com/gatsbyjs/gatsby-starter-blog
+    ```
+
+1.  **Start developing.**
+
+    Navigate into your new site’s directory and start it up.
+
+    ```shell
+    cd my-blog-starter/
+    gatsby develop
+    ```
+
+1.  **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.com/docs/tutorial/part-4/#use-graphiql-to-explore-the-data-layer-and-write-graphql-queries).
+
+    Open the `my-blog-starter` directory in your code editor of choice and edit `src/pages/index.js`. Save your changes and the browser will update in real time!
+
+## 🚀 Quick start (Gatsby Cloud)
+
+Deploy this starter with one click on [Gatsby Cloud](https://www.gatsbyjs.com/cloud/):
+
+[<img src="https://www.gatsbyjs.com/deploynow.svg" alt="Deploy to Gatsby Cloud">](https://www.gatsbyjs.com/dashboard/deploynow?url=https://github.com/gatsbyjs/gatsby-starter-blog)
+
+## 🧐 What's inside?
+
+A quick look at the top-level files and directories you'll see in a typical Gatsby project.
+
+    .
+    ├── node_modules
+    ├── src
+    ├── .gitignore
+    ├── gatsby-browser.js
+    ├── gatsby-config.js
+    ├── gatsby-node.js
+    ├── gatsby-ssr.js
+    ├── LICENSE
+    ├── package.json
+    └── README.md
+
+1.  **`/node_modules`**: This directory contains all of the modules of code that your project depends on (npm packages) are automatically installed.
+
+1.  **`/src`**: This directory will contain all of the code related to what you will see on the front-end of your site (what you see in the browser) such as your site header or a page template. `src` is a convention for “source code”.
+
+1.  **`.gitignore`**: This file tells git which files it should not track / not maintain a version history for.
+
+1.  **`gatsby-browser.js`**: This file is where Gatsby expects to find any usage of the [Gatsby browser APIs](https://www.gatsbyjs.com/docs/reference/config-files/gatsby-browser/) (if any). These allow customization/extension of default Gatsby settings affecting the browser.
+
+1.  **`gatsby-config.js`**: This is the main configuration file for a Gatsby site. This is where you can specify information about your site (metadata) like the site title and description, which Gatsby plugins you’d like to include, etc. (Check out the [config docs](https://www.gatsbyjs.com/docs/reference/config-files/gatsby-config/) for more detail).
+
+1.  **`gatsby-node.js`**: This file is where Gatsby expects to find any usage of the [Gatsby Node APIs](https://www.gatsbyjs.com/docs/reference/config-files/gatsby-node/) (if any). These allow customization/extension of default Gatsby settings affecting pieces of the site build process.
+
+1.  **`gatsby-ssr.js`**: This file is where Gatsby expects to find any usage of the [Gatsby server-side rendering APIs](https://www.gatsbyjs.com/docs/reference/config-files/gatsby-ssr/) (if any). These allow customization of default Gatsby settings affecting server-side rendering.
+
+1.  **`LICENSE`**: This Gatsby starter is licensed under the 0BSD license. This means that you can see this file as a placeholder and replace it with your own license.
+
+1.  **`package.json`**: A manifest file for Node.js projects, which includes things like metadata (the project’s name, author, etc). This manifest is how npm knows which packages to install for your project.
+
+1.  **`README.md`**: A text file containing useful reference information about your project.
+
+## 🎓 Learning Gatsby
+
+Looking for more guidance? Full documentation for Gatsby lives [on the website](https://www.gatsbyjs.com/). Here are some places to start:
+
+- **For most developers, we recommend starting with our [in-depth tutorial for creating a site with Gatsby](https://www.gatsbyjs.com/tutorial/).** It starts with zero assumptions about your level of ability and walks through every step of the process.
+
+- **To dive straight into code samples, head [to our documentation](https://www.gatsbyjs.com/docs/).** In particular, check out the _Guides_, _API Reference_, and _Advanced Tutorials_ sections in the sidebar.
+
+## 💫 Deploy
+
+[Build, Deploy, and Host On The Only Cloud Built For Gatsby](https://www.gatsbyjs.com/products/cloud/)
+
+Gatsby Cloud is an end-to-end cloud platform specifically built for the Gatsby framework that combines a modern developer experience with an optimized, global edge network.

+description: "Hello World"
+---
+
+This is my first post on my new fake blog! How exciting!
+
+I'm sure I'll write a lot more interesting things in the future.
+
+Oh, and here's a great quote from this Wikipedia on
+[salted duck eggs](https://en.wikipedia.org/wiki/Salted_duck_egg).
+
+> A salted duck egg is a Chinese preserved food product made by soaking duck
+> eggs in brine, or packing each egg in damp, salted charcoal. In Asian
+> supermarkets, these eggs are sometimes sold covered in a thick layer of salted
+> charcoal paste. The eggs may also be sold with the salted paste removed,
+> wrapped in plastic, and vacuum packed. From the salt curing process, the
+> salted duck eggs have a briny aroma, a gelatin-like egg white and a
+> firm-textured, round yolk that is bright orange-red in color.
+
+![Chinese Salty Egg](./salty_egg.jpg)
+
+You can also write code blocks here!
+
+```js
+const saltyDuckEgg = "chinese preserved food product"
+```
