-_You turned on GitHub Pages! :tada:_
+_Nice work setting the theme! :sparkles:_
 
-We'll work in a branch, `my-pages`, that I created for you to get this site looking great. :sparkle:
+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.
 
-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.
