Reading time

Hi, how are you? Our catch themes website: www.conducere.com.br I'm trying to set up in our blog a plugin for reading in a progress bar. I found the "Worth The Read". However, I could not get the result I wanted. I am sending you an image of a reading from Harvad Business Rewiew Brazil. I would like our Blog to stay this way, that is, with the progress track, the track title and this "15 minute" marker. The site that I removed this image is the: http://hbrbr.uol.com.br/a-inovacao-esta-onde-voce-menos-espera/ Is this some programming or plugin other than what I'm using? Thank you, Big hug, Valeska
