Once the installation is completed, the Science-X theme is ready for the first use. Now you can navigate to Appearance > Themes and activate the Science-X theme. After completing this, you should find the theme name Science-X in the existing Themes menu. Locate it and just click on the ‘Activate’ button (if the theme was uploaded via FTP).
Or click Activate right after the theme was installed (if it was installed with Theme Uploader)
After you have done this, you should also see the notification that appears in the left navigation bar of your WordPress admin panel. It requires plugins that need to be installed. Please install and activate all of the required plugins, since they are necessary for the theme to function properly
