confused about child-theme

i have some question.

after install main theme, Should will i install child-theme?

Thank you.

Child theme is only needed if you intend to customize the templates by hand. 🙂

WordPress documentation:
https://codex.wordpress.org/Child_Themes

A WordPress child theme is a theme that inherits the functionality of another theme, called the parent theme. Child themes allow you to modify, or add to the functionality of that parent theme. A child theme is the safest and easiest way to modify an existing theme, whether you want to make a few tiny changes or extensive changes. Instead of modifying the theme files directly, you can create a child theme and override within.
