fundamental tutorials

Hi,
I haven't found fundamental tutorials on Candle, it looks like the target audience of Candle are veterans on deep learning . Could anyone provide some tutorials on candle (or even basic knowledge on machine learning) for beginners to follow step by step ?

The issue names no files, tests, or entry points. First inventory Candle's current documentation and examples to identify the missing beginner path, then define a step-by-step tutorial scope covering basic machine learning and Candle usage. Done means the agreed beginner tutorials are published and usable without prior deep-learning expertise.
