MIT license when adding new content type

Content creation

When I deploy new content type into my site, I'll get the MIT license notification. What do these two last sentences mean practically:
(translated from Finnish)

 - Copyright must be included
 - License must be included

What do I have to do when using these content types, or do I have to do anything?

Thanks again in advance for your quick reply :)
