How do you get the skype icon to pin to your taskbar at the bottom?

I dont want to get rid of it, but my friend has just got skype and she goes onto google and enters skype, logs in but cant talk to contacta because the icon doesnt appear at the bottom of the screen. So she can’t see her contacts or anything. I have skype too but mine appears and I can’t remember how I did it! Please really need help with this! Thankyou!
