Could you do icons update in the "DOCUMENTATION"?

Please, could you update icons and pictures in the description area ? (https://sleep.urbandroid.org/documentation/core/background/#understanding-sleep-graphs) App has many functions and it is confusing for the new users to understand which icons on their graphs stands for which in your description. There is no icon mentioned in the descrioption as smart wake up in the legend area on my mobile and also smart wake up period that is supposed to be red hashed line looks like grey hashed line (and there are 2 of them on one graph). I may be wrong of some of the above but it only indicates that the desctioption is not clear enough (no description of the grey hashed line).

smart%20wake%20up !

Thanks a lot, please keep us alert with such update requests! We’re planning to focus on updating the documentation during April so this will be done as well.
