Karolina, please tell us what you're using it for. Its often seen in two ways; (1) the skeleton of 3-D objects and environments, the movement specs in animation and in vector based design (Illustrator) -and- (2) an outline used in presentations (Powerpoint) -- and a useful way to help programmers and designers think and communicate about the structure of the software (especially UI and UX) ...

Thank you for your answer. I am not actually working on anything, so I can't specify the intention of use. I was mostly interested in some advice where to start in general.

Karolína Trojanovičová Karolina, You can go to your local library and/or use Google and Google Scholar and ask what is “wireframe design”. -- Your first task is finding if this is what you’re thinking about. That is, find out if this is your question or are you really wondering about something else. -- For example; both “information graphics” and “concept mapping” & prototype design represent forms of wire frame design. But designing digital objects made of 3-D wireframes, animating movement or the underlying wireframes in 2-D digital illustrations are a specific form of wireframe design. I suggest starting with "information graphics". Look for Edward Tufte's ideas and books on the topic.

Lee Clawson Thank you very much for your answer and advice. It is very helpful. I will definitely look into it more.
