Next, in your site’s WordPress dashboard, go to Appearance > Themes, click ‘Add New’ button and then on next page click ‘Upload Theme’ and using the ‘Browse’ button to select the Trusted Pro theme file (trusted-pro.1.0.5.zip) you previously downloaded, and click ‘Install Now’.
Once the theme has been installed you should see something like this:

Then click ‘Activate’ to activate Trusted Pro.
If you have already been using Trusted (the free version) you can copy your theme customizations into Trusted Pro by going to the ‘Theme Mods’ area in your dashboard – the link is just above ‘Appearance’ in the dashboard’s menu – and click the ‘Import from Trusted’ button.
