Hai all,
When we share the apps in any social media like facebook, linkedin, twitter we need good card to showcase our module. I just share a https://apps.odoo.com/apps/modules/10.0/game_sudoku/ module link in twitter but its look like this. No cards or image or description to show. 

There is no metadata for modules. there is no cards.

Anyone know any solution to add metadata to the modules in odoo apps. Share your ideas. 
Thanks in advance.
