This question already has an answer here:
I have resigned my old employer to start a new job, and I need to prepare a handover [documentation to be taken by some new employee that haven't arrived yet, and would be some weeks from when I go to when they fill the position again].
So what important points should I make sure to cover,
I was making some iOS apps, [90% completed], and a web portal [60% completed]
the other IT engineer is here so he can update on passwords etc.
Should I use some system like a wiki to leave things there for access? or just a normal doc?
what other things should I consider?
