Summary is a short description of certain situation, event, book red and etc. It’s used to transform a material into short text, including most important facts. It’s used as well, when we relate something. Very useful in science thesis. You can mostly see summaries of literary texts and science/popular science articles.
Exit point for summary is always some sort of text, with which you have to meet. Don’ discourage yourself, if you won’t understand red text from the start. There are articles, which you have to read two or three times, to fully understand then, and it’s a pretty common thing.
Goal of summary is including most important arguments from original world, in a way, to keep its original meaning. Summary is consistent and firm with author thought in original text, this is not a place for subjective feelings or opinions.
Qualities of a good summary:
should be short, concrete and tight;
should consider only a topic, you want to summarize;
should include most important, basic threads;
should constitute the essence of summarized work;

digression, personal comments;
copying words/text from original (you must summarize it with your own words, no to compile with elements of original).
