Portfolio like in the demo-version

Hi there,

the homepage of the Illustratr theme is set up using the portfolio feature included in the Jetpack plugin, so as a first step you will want to add Jetpack, and then activate the portfolio custom post type.

Once you have done that you will need to add items to the portfolio section of your site (added by the Jetpack plugin) and then you can follow the steps here to set up your theme same as the demo: https://wordpress.com/theme/illustratr/

Hope this helps!
