I’ll be submitting an update this morning that allows the theme to work with Jetpack’s (http://jetpack.me/) Featured Content functionality. I’ll update the README.md to reflect this.
Once the new version is available, you can enable the slider by installing Jetpack and then:
1. Navigate to Settings → Reading.
2. Scroll down to the section labeled “Featured Content”.
3. Enter the name of a tag.
4. Click the blue “Save Changes” button at the bottom.
5. Once a tag name has been saved, posts having this tag will appear in the featured content section.
Installing Jetpack will also give you access to other awesome features like Infinite Scroll, Tiled Galleries, Sharing, and Post Likes.
