May be it will be interresting for somebody:
https://github.com/DnCraptor/pico-class/
it contains Russion and English readme. For main topics (program modules) - let use online translator or AI.
Actually all required already done (see https://github.com/DnCraptor/pico-class/tree/main/hardware/olimex-pico-pc), so, it is just to highlight that it exists, and may be useful for Olimex customers.
