It is a good idea indeed.

I agree.

Olzhas, please get familiar with and try to follow the guidelines from:

Yes, we need to synchronise.

Miral, if you see any clash with the work you've planned, please let
Olzhas/us know.

about documentation.
Miral will write prose about image processing algorithms in

Regarding code structure, I think we will need similar, i.e.
