Adding about page and contact page

Help. Im a NOOB. I have looked throughout the forums to see if there is a place that show how to add simple pages and edit the information on the page. I need to add About us, Services, News, Contact, Home but I dont see anything in the admin. When I log on to the site its just the login area and site name. Please if anyone want to help I can give them access to look at the site. It seems to be installed corectly. I even was able to change the theme.
