could not find "/usr/local/nginx" after yum install nginx

[756323342]

hello,i'm new to nginx.
i'm using "yum" to install nginx.i followed the
instruction(http://wiki.nginx.org/Install),and added repository for nginx.
After i finished it,i can't find this directory(/usr/local/nginx).but in the
page(http://wiki.nginx.org/InstallOptions),it tells me that
"/usr/local/nginx directory by default"

i don't know why.is that possible that the Doc in wiki is for the older
version?
