BOM and nice-to-have docs Missing,

[The-May]

Hi i stumbled upon this awesome sounding project
I am not too experienced into transcribing which components are needed but from what I have read out from the libs you need:

esp32cam-board (duh)
SSD1306 display (see ProgramService)
buttons (see ButtonService)
battery (see BatteryreaderService)
sd-card+reader (see SaveService)

am I missing something out?

can you maybe specify what exactly you have used to maybe rebuild it and can you maybe provide a brief explanation what has been wired where?

Thanks in advance
