Nginx wordpress-ms-subdomain.conf

Hi,

I am trying to follow this guide to setup wordpress subdomain multisite: https://codex.wordpress.org/Nginx

In the guide it includes the rewrite rules like so:

# Only include one of the files below.
	include global/wordpress.conf;
#	include global/wordpress-ms-subdir.conf;
#	include global/wordpress-ms-subdomain.conf;

The guide includes the full file for wordpress.conf and wordpress-ms-subdir.conf but does not include wordpress-ms-subdomain.conf.

I am really struggling translating the apache rewrite rules to Nginx because I am new to Nginx and have not used apache.

When I google it I get various conf files but none of them have the correct multisite re-write rules as I assume people are using Nginx as a reverse proxy maybe I am not sure.

I am using Nginx + PHP-FPM so I need to translate the rewrite rules to Nginx. I am sure this has been done many times before but I cannot find them.

Does anyone know of a working conf for multisite subdomain?
