-## Start the node.js server
+## Setup local development environment
+**Install Nginx.**
+
+	sudo apt-get install nginx
+
+If you have apache installed, remove apache or edit `/etc/apache2/ports.conf`
+change `Listen 80` to `Listen [any usable port other than 80 and 8080]`
+restart apache and nginx
+
+	service apache2 restart
+	service nginx restart
+
+**Install npm and node.js**

+
+	cd [project directory]
+	npm install

+Server config file can be found in project root directory.

+To enable the site, symbolic link test.uwacg to /etc/nginx/sites-enabled
+
+	sudo ln -s /etc/nginx/sites-available/test.uwacg /etc/nginx/sites-enabled
