I'm new to Drupal 8. 

I need to let users to create new node of some content type by pressing a button or custom link. In Drupal 7 I could achieve this by *Rules* and *Rules link* modules but I can't figure out how to do it in D8.

Let's assume I have a content type where all fields have default values and I want to create new node of this content type just by pressing a custom button. 

How can I get this working in D8? Any tips?
