Hi,

That's quite easy, so we don't put it to documentation.

To use reviews system, please do following steps:

1/ Make sure you've actived plugin Penci Pennew Review - If not, go to Appearance > Install Plugins > and install & active it.

2/ Go to edit a post, scroll down and you can see options for create a review - let's fill all the point you want for your review. Example a product has some points like: Designs, Reliability, Handling...

When you filled all the fields you want. Use the shortcode like on this image and put it to anywhere inside your editor - where you want the review appears.

Here is an example of review:
