You can place this above the short code, fill in the info in the brackets and remove the start and end brackets.
You can also add an image of 5 stars with the caption showing the aggregate score by dividing the total number of reviews by the total number of 1 to 5 stars.
IE.
15 five stars
3 four stars
2 one stars
= 89 divided by 20 (stars total)for aggregate rating of 4.45 stars. hope that helps.
