Can you explain the meaning of the expression "what to do in what order" in this paragraph?
i'm not native speaker and i'm reading a book how to improve your English. The writer said that you should meet more foreigners. But the book has a confusing paragraph. Here is the paragraph:
"But by adopting the communication traits that I present straight away, you will accelerate your progress tremendously, and you will no longer need detailed step-by-step instructions for how to meet foreigners and what to do in what order, although Part IV will still provide that for you."
Can you explain the meaning of the expression "what to do in what order" in this paragraph? Thank!

Question

Answer

The author is giving you a step by step list of actions you would do, in a sequence - meaning you do action #1, then action #2, then action #3.  You do them in that sequence at the beginning of learning how to interact with foreigners.  
(part IV of the book gives you the list of steps to follow).
BUT...  Through experience, you will know what to do first, and then what to do next.  You will be independent.  If this still does not make sense, let me know.

Answer

"Tell me what to do." 
"Thaw the pumpkin pie, roast the turkey, and pour the cider."

"Tell me what to do in what order."
"First, about three hours before dinner, preheat the oven to 350°F and then put the turkey in. Second, about an hour before dinner, take the frozen pumpkin pie out of the freezer and put it on the counter to thaw. Third, just before everyone sits down, put the glasses on the table and pour the cider."

Often, it doesn't matter what order things are done in. Here, he's just using the phrase "what to do in what order" to suggest very specific, detailed directions.
