Documentation about PPOCRv3 config files

[suheylkiris]

Hi,
When i have read Training Det/Rec Model subtopics, there is linked section which forward to config file documents. But the config documentations are written before ppocr_v3. So when i look into configs/det/ch_ppocrv3 there are different types config files like cml, dml and student and they are includes different blocks like teacher/student etc. Is there any GUIDE documentation about for v3 config files. If not, how can i learn meaning this blocks and how to configure them.
