The theme can be configured (and more options can be added as you develop your own theme) with either an Options page or with Customizer in live preview mode. Both methods have been added by default in Inti Foundation so that you can choose which you’d prefer to you for your own options. By default, options that are more to do with global settings have been added to an Options page called “Inti Options” and options that are more to do with visual elements have been added in Customizer. Feel free to modify these as you see fit.
Have a look around and set the options activate elements in the theme. Perhaps the most important area is found in the Customizer and relates to the header area.
