How to update the new Features in Product Hunt

Hi hi, we have launched summymonkey months ago, but we have been enhancing the features. How can I update my product description? I would really love you to know that we have a cool features in summymonkey now - get the summary and transcript of a youtube just by submitting the youtube link. You can try out by sending a youtube link (just the link itself and nothing else) to sm+test@summymonkey.me to try it out. If you think it is useful and have hit the maximum number of time, just sign up and you will get 60 credits. Hope to get your support. We will also roll out 2 additional features this week, so would really like to know the proper way to update. Thanks for the advice!
