What to do with nginx when installing Passenger?

Question

Nginx

I'm trying to install Passenger on a server. I got to the point where you need to write to the console:

passenger-install-nginx-module

You are then given a choice between two types of installation:

Do you want this installer to download, compile and install Nginx for you?
1. Yes: download, compile and install Nginx for me. (recommended)
The easiest way to get started. A stock Nginx 1.10.1 with Passenger
support, but with no other additional third party modules, will be
installed for you to a directory of your choice.
2. No: I want to customize my Nginx installation. (for advanced users)
Choose this if you want to compile Nginx with more third party modules
besides Passenger, or if you need to pass additional options to Nginx's
'configure' script. This installer will 1) ask you for the location of
the Nginx source code, 2) run the 'configure' script according to your
instructions, and 3) run 'make install'.

If you select item 2, then:

Where is your Nginx source code located?

That is, again, compiling and installing nginx (essentially the first point, only here everything is done manually).
At this point, I have my doubts. I already have the Apache + nginx bundle installed on the server, and there are also changes in nginx.conf.
What do i do? What to do?
