+## Usage
+
+You can use these sample configurations as reference or directly by replacing your existing nginx directory. Follow the steps below to replace your existing nginx configuration.
+
+Backup any existing config:
+
+`sudo mv /etc/nginx /etc/nginx.backup`
+
+Clone the repo:
+
+`sudo git clone https://github.com/A5hleyRich/wordpress-nginx.git /etc/nginx`
+
+Symlink the default file from _sites-available_ to _sites-enabled_, which will setup a catch-all server block. This will ensure unrecognised domains return a 444 response.
+
+`sudo ln -s /etc/nginx/sites-available/default /etc/nginx/sites-enabled/default`
+
+Copy one of the example configurations from _sites-available_ to _sites-available/yourdomain.com_:
+
+sudo cp /etc/nginx/sites-available/singlesite.com /etc/nginx/sites-available/yourdomain.com`
+
+Edit the site accordingly, paying close attention to the server name and paths.
+
+To enable the site, symlink the configuration into the _sites-enabled_ directory:
+
+`sudo ln -s /etc/nginx/sites-available/yourdomain.com /etc/nginx/sites-enabled/yourdomain.com`
+
+Test the configuration:
+
+`sudo nginx -t`
+
+If the configuration passes, restart Nginx:
+
+`sudo /etc/init.d/nginx reload`
