This theme is designed for Concrete 5.5.1 and above. It has Global areas defined which call in Stacks.

The responsive images mentioned in the description will scale an image down as you resize the window or view on a smaller device but will not scale a small image up.

Free bundled slider works using sets. If your images are different sizes, set a height in the Edit Block menu and slider will do the rest.

Additional Global content areas have been set up in the theme which will automatically create blocks named as the following:

Additional_Info: (additional content below Nav)
Footer_Middle: (additional content for middle section of footer)
Footer_Right: (additional content for right hand side of footer)
