Cannot Install Theme

Hello I cannot install this theme on my site:

The package could not be installed. The theme is missing the style.css stylesheet.

Theme installation failed.
Please help. Thanks!


Only items labelled “Elementor Template Kit” can be installed using the Template kit import plugins. If ou have a WordPress theme, it must be installed under Appearance > Themes > Add New


So it means I will install Elementor on my site before installing the theme?
