Where can I find documentation?

Hi, I’ve just started using the pico and purchased an explorer base.
Where can I find data about how it works and how I can use it.

Try here:
pimoroni-pico/micropython/modules/pico_display at main · pimoroni/pimoroni-pico · GitHub

and here:
Raspberry Pi Pico & Pico Explorer Workout : 15 Steps - Instructables

Hi @tonygo2 Thanks for this pointer.
Plenty to work through.
