@Samuelgozi - There’s really not a “right” or “wrong” directory, so to speak. Different NGINX packages will use various directories ranging from
/usr/share/nginx/html/ all the way up to the more custom setups which will use one or more user-defined directories.
Ultimately, you’re free to choose where you place your files, just make sure that the directories have the proper permissions set to allow NGINX to access the files (as well as whatever scripting language you choose to run).
On a personal level, I prefer to use
[custom-directory-string] is whatever is applicable to the project or client needs. The
/home/ directory is the default home directory on most all OS’s and it’s easily identified when a client is browsing through.
