Hi everyone! So I'm new to nginx and want to change my document root directory from "root /usr/share/nginx/html" to "home/user101/box/developments" . How do I do it? Thanks!

Change the document root directive, in nginx.conf or your_site.conf, both of these files are available in the directory where you installed nginx (/etc/nginx in my case) The document root directive may be inserted under the server block as. You can define it thus
root /usr/share/nginx/www;

I found this line
root /usr/share/nginx/html;
from
/etc/nginx/sites-available/default
I think that's right? I changed the path to /home/user101/box/development
I am receiving forbidden and "No files specified"
How can I fix it? What is the right permission I need on the folders/files?
Also I've seen this line at nginx.conf -> user www-data;

Thanks for replying!

Also change the root directive in /etc/nginx/sites-enabled/ whichever conf file is here.
Make sure you pass the index directive too, so that nginx knows what is the index file for the root directory. You can pass it thus
index index.htm index.php;

This should be enough to make your setup work :)
