As codebase gets large it becomes painful to grasp and work on. Now with remote culture the chances of pulling coworker to side and asking quick questions seem to be out of the window.I was thinking gee i'd have loved if the senior dev in my company just made a video explaining throughly how everything is setup, what does this do and why?I've not fully thought out this, but I was thinking what if there was a systematic way a company could be brought in to document and then create tutorials one the code which then can be used by new hires or even devs who are new to the area.Questions the videos could address...- how is this setup? where does the data come from and where does it go..- what does this variable do?- why are we doing this?sadly wont be able to answer...i want to do xyz, where should i look?but still I feel there is clear value in video tour of codebase, like a video tour of house and how all is connected.
