Child Theme

First of all, not everyone needs a child theme. If you need to modify PHP files of the theme like adding more functions or alter some functions of the theme, then you should use child theme because in each update, the updated version will override all changes you made in PHP, CSS, JS files in fox directory (of course, database stuffs like posts, pages, content, images.. are safe under updates but theme files are not).
