you need to install Skype first in your computer or device. First go to the downloads section of Skype.com (http://www.skype.com/en/download-skype/) and download the installer for your computer or mobile device. Then after installing it, you can use the basic and advance features of Skype such as calls, video calls, chat, etc, etc.
Visiting the user guide section might also help -
