Configure Github to automatically push to server

We recently set up github on the staging site for an ecommerce website. Our website runs on Opencart which is hosted on a Centos server. To complete the job, you will need you to do the following: - Configure the files on github to automatically push to our staging site on the server. - Grant permissions to groups on the server so developers have access to certain folders. - Ensure that our live site can successfully pull files from Github to the server. (This will be done in next week at night, USA time. We will schedule a time that works for you and our developer.)
