申请父母绿卡 checklist and workflow

I think this question must be asked many times, but WXC search engine really sucks.

Can anyone kindly point me to link(s) of checklist and workflow for a US citizen to apply GC for his/her parents. Checklist should include a list of artifacts (I-130, 485 etc.), and workflow should include when to submit what, what to expect in return, etc. 

The uniqueness of my case: Father in US now as visitor, Mother in China.

You do not have to elaborate action items here. Links will be highly appreciated. 

Many Thanks
