Meta images are the visuals displayed when you share your API documentation link on social media. You can use your own image or Bump can generate one for you.
From your dashboard, select the documentation you would like to edit. If this documentation belongs to a hub, you'll need to select the hub directly.
From the documentation settings, select Customize UI, reach the Social Media section and upload or drop the image you would like to use.
In case you wouldn't have a visual you could use, Bump will automatically generate an image for social media. This visual display your documentation name (or the hub name, in such case), its logo and its type.
