Here are notes from our today's discussion re docs improvement:

• add an option to display the docs in high-contrast mode (likely a feature that could be actually added to pdoc itself)

• disable menu icon (visible if browsing on mobile devices) for the project landing page (where there is no menu)

• enrich visually the algorithm description (could be linked with incorporation of numerics-related tutorial content)

• identify the audience of the docs and ensure that relevant content is present (e.g., student new to MPDATA; someone familiar with MPDATA; someone unfamiliar with Numba, ...)

• add a reference-list page with automatic checks if all DOIs used in the docs are mentioned there

• add a Credits page acknowledging contributions with developer identities

• add logos (AGH, Numba, numba-mpi, NCN, FNP, ...)

• add on the homepage a list of MPDATA variants implemented with surname-labeled links to the relevant papers

• move logo files in the repo from .github folder to docs folder

• repeat what is relevant from the above for PySDM, PyPartMC, numba-mpi, PyMPDATA-MPI

• max width for images: 100% #482

Found something interesting regarding dark mode/high contrast mode for pdocs, might be worth considering
