For a good summary you will need 3 main things, conciseness, accuracy, and objectivity. If you do all of these you will have yourself a good summary. But to get more in depth with it. You should always put the most important details. Like if you read a story about a cat stuck in a tree. You just put the main things, any extra detail like, what color the cat is or what type of tree it is. All of that is not needed. Just the main things about the story will do you fine.
A good summary requires conciseness, accuracy, and objectivity. Including only the most important details is crucial, disregarding unnecessary information such as the cat's color or the type of tree.
