Build a webpage with custom fake news to share on Facebook

I have seen a very funny and cool website that I really want to do something similar to it. The problem with the website is that it have horrible design and a lot of bugs. And it is missing a lot of fuctions that I want to ad. I have the website url if you want to look at it. It is very simple, without so much knowledge I will try to explain what it does: Users upload a image that will be on a new website and on the og:image as title and description to the og:title and og:description and they can share this on Facebook and it will look like a good new. I have the URL if you want to take a closer look, It is really hard for me to explain I think you need to check by your self. Thanks.
