Once the plugin is installed and activated, go to the new Reviews page in your WordPress admin area.
To add a new review, click the Add New link at the top of the page. You’ll see a familiar page where you can enter all of the review details.
Enter the reviewer’s name at the top, where you’d normally put a post title.
I would encourage you to add a link to the review under Review Link, if it exists elsewhere on the web. This is good practice for SEO and makes the review seem more reliable.
The Featured Image should be used to add a profile image for the reviewer if you have one.
Once you’ve added a few reviews, you’ll probably want to display them on your site.
