+
+## Step 1: Enable GitHub Pages
+
+_Welcome to GitHub Pages and Jekyll :tada:!_
+
+The first step is to enable GitHub Pages on this [repository](https://docs.github.com/en/get-started/quickstart/github-glossary#repository). When you enable GitHub Pages on a repository, GitHub takes the content that's on the main branch and publishes a website based on its contents.
+
+### :keyboard: Activity: Enable GitHub Pages
+
+1. Open a new browser tab, and work on the steps in your second tab while you read the instructions in this tab.
+1. Under your repository name, click **Settings**.
+1. Click **Pages** in the **Code and automation** section.
+1. Ensure "Deploy from a branch" is selected from the **Source** drop-down menu, and then select `main` from the **Branch** drop-down menu.
+1. Click the **Save** button.
+1. Wait about _one minute_ then refresh this page (the one you're following instructions from). [GitHub Actions](https://docs.github.com/en/actions) will automatically update to the next step.
+   > Turning on GitHub Pages creates a deployment of your repository. GitHub Actions may take up to a minute to respond while waiting for the deployment. Future steps will be about 20 seconds; this step is slower.
+   > **Note**: In the **Pages** of **Settings**, the **Visit site** button will appear at the top. Click the button to see your GitHub Pages site.

+
+## Step 2: Configure your site
+
+_You turned on GitHub Pages! :tada:_
+
+We'll work in a branch, `my-pages`, that I created for you to get this site looking great. :sparkle:
+
+Jekyll uses a file titled `_config.yml` to store settings for your site, your theme, and reusable content like your site title and GitHub handle. You can check out the `_config.yml` file on the **Code** tab of your repository.
+
+We need to use a blog-ready theme. For this activity, we will use a theme named "minima".
+
+### :keyboard: Activity: Configure your site
+
+1. Browse to the `_config.yml` file in the `my-pages` branch.
+1. In the upper right corner, open the file editor.
+1. Add a `theme:` set to **minima** so it shows in the `_config.yml` file as below:
+   ```yml
+   theme: minima
+   ```
+1. (optional) You can modify the other configuration variables such as `title:`, `author:`, and `description:` to further customize your site.
+1. Commit your changes.
+1. (optional) Create a pull request to view all the changes you'll make throughout this course. Click the **Pull Requests** tab, click **New pull request**, set `base: main` and `compare:my-pages`.
+1. Wait about 20 seconds then refresh this page (the one you're following instructions from). [GitHub Actions](https://docs.github.com/en/actions) will automatically update to the next step.

+
+## Step 3: Customize your homepage
+
+_Nice work setting the theme! :sparkles:_
+
+You can customize your homepage by adding content to either an `index.md` file or the `README.md` file. GitHub Pages first looks for an `index.md` file. Your repository has an `index.md` file so we can update it to include your personalized content.
+
+### :keyboard: Activity: Create your homepage
+
+1. Browse to the `index.md` file in the `my-pages` branch.
+1. In the upper right corner, open the file editor.
+1. Type the content you want on your homepage. You can use Markdown formatting on this page.
+1. (optional) You can also modify `title:` or just ignore it for now. We'll discuss it in the next step.
+1. Commit your changes to the `my-pages` branch.

+
+## Step 4: Create a blog post
+
+_Your home page is looking great! :cowboy_hat_face:_
+
+GitHub Pages uses Jekyll. In Jekyll, we can create a blog by using specially named files and frontmatter. The files must be named `_posts/YYYY-MM-DD-title.md`. You must also include `title` and `date` in your frontmatter.
+
+**What is _frontmatter_?**: The syntax Jekyll files use is called YAML frontmatter. It goes at the top of your file and looks something like this:
+
+```yml
+---
+title: "Welcome to my blog"
+date: 2019-01-20
+---
+```
+
+For more information about configuring front matter, see the [Jekyll frontmatter documentation](https://jekyllrb.com/docs/frontmatter/).
+
+### :keyboard: Activity: Create a blog post
+
+1. Browse to the `my-pages` branch.
+1. Click the `Add file` dropdown menu and then on `Create new file`.
+1. Name the file `_posts/YYYY-MM-DD-title.md`.
+1. Replace the `YYYY-MM-DD` with today's date, and change the `title` of your first blog post if you'd like.
+   > If you do edit the title, make sure there are hyphens between your words.
+   > If your blog post date doesn't follow the correct date convention, you'll receive an error and your site won't build. For more information, see "[Page build failed: Invalid post date](https://docs.github.com/en/pages/setting-up-a-github-pages-site-with-jekyll/troubleshooting-jekyll-build-errors-for-github-pages-sites)".
+1. Type the following content at the top of your blog post:
+   ```yaml
+   ---
+   title: "YOUR-TITLE"
+   date: YYYY-MM-DD
+   ---
+   ```
+1. Replace `YOUR-TITLE` with the title for your blog post.
+1. Replace `YYYY-MM-DD` with today's date.
+1. Type a quick draft of your blog post. Remember, you can always edit it later.
+1. Commit your changes to your branch.
+1. Wait about 20 seconds then refresh this page (the one you're following instructions from). [GitHub Actions](https://docs.github.com/en/actions) will automatically update to the next step.
