A WordPress theme is an element that is responsible for the appearance of the website. It is what makes a portfolio (e.g. of your projects) or a recipes appear on your website. If you are wondering how to install a theme in WordPress, let us reassure you – it’s a very simple operation ? In the instructions below, you will see how to install a theme from both the official theme directory and your computer (if the theme is made by an external development team like Astratic).

Themes play an important role on your website. Thanks to them, in a few clicks you get a new look for your website without coding. You can use free themes or install a business theme for this.
