My htaccess goes like so:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www.)?audino.us$
RewriteCond %{REQUEST_URI} !^/audino.us/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /audino.us/$1
RewriteCond %{HTTP_HOST} ^(www.)?audino.us$
RewriteRule ^(/)?$ audino.us/index.php [L]

I got web hosting under the domain audino.us which defaults to public_html dir on server, how do I set it to serve public_html/audino.us without repeating itself? (i.e., audino.us/audino.us/page-name) Homepage loads just fine but when I try accessing the backend for example I encounter the parenthesised. Thanks
