Billie is a responsive, accessibility-ready theme. The theme has two optional menus (including a social menu) two different sidebars and a footer widget area that will hold any number of widgets.
Features also include a Call To Action button and custom copyright text. I recommend that you install the Jetpack plugin to make full use of supported features like logos, featured content, contact forms, testimonials, social sharing and more.
To create a portfolio, install Jetpack and create your projects, all the templates are already shipped with the theme. Billie also works well with Woocommerce and bbPress.
