I already installed the Soledad and Soledad Child theme in my Wordpress and inside the downloaded folders I have already find the "herbal-tea-multipurpouse.dat" file that I suppose contains the look that made me purchase the theme in the first place.

The problem is that I can't find a tutorial or any resource to know how to  upload that file into my Wordpress CMS to install all the plugins to make my blog look like the herbal-tea design.

Can you help me?
