You can install a new WordPress theme without having any technical knowledge. It's so easy and automated. This tutorial assumes that you do not have a ".zip" file and that you want to download and install it from WordPress itself.
If you have a ".zip" file, please follow our other tutorial about manually installing a WordPress theme.
1. Log in to your WordPress admin dashboard.
2. Under the dashboard menu, hover your mouse over "Appearance" and then click on "Themes".
3. Click on "Add New".
4. In the Add Themes page, you can search for a theme or browse the themes from the "Featured", "Popular", "Latest" options. If you hover your mouse over any theme, you will be presented with two options - "Install" and "Preview". Preview lets you live preview it without installing it first.
5. Hover your mouse over any theme that intrigues you and then click on "Install".
6. A newly installed theme will show you the "Activate" option. Click it!
Congratulations, you have installed and activated a new theme on your website.
