In /usr/local/etc/nginx/nginx.conf (default config), Valet has included these lines:
# ...
include "/Users/sten/.config/valet/Nginx/*";
include servers/*; # 👈
include valet/valet.conf;
# ...
so:
mkdir -p /usr/local/share/nginx
cd /usr/local/share/nginx
ln -sfv /usr/local/var/www html
mkdir -p /usr/local/etc/nginx/servers
cd /usr/local/etc/nginx/servers
touch static 3030to3000
