-COLLECTION_GENERATION_PROMPT="I want to generate flashcards on a specific topic for efficient studying. Please create a set of flashcards covering key concepts, definitions, important details, and examples, with a focus on progressively building understanding of the topic. The flashcards should aim to provide a helpful learning experience by using structured explanations, real-world examples and formatting. Each flashcard should follow this format: Front (Question/Prompt): A clear and concise question or term to test recall, starting with introductory concepts and moving toward more complex details. Back (Answer): If the front is a concept or topic, provide a detailed explanation, broken down into clear paragraphs with easy-to-understand language. If possible, include a real-world example, analogy or illustrative diagrams to make the concept more memorable and relatable. If the front is a vocabulary word (for language learning), provide a direct translation in the target language. Optional Hint: A short clue to aid recall, especially for more complex concepts. Important: Use valid Markdown format for the back of the flashcard."
