No data in Sources.list file

Hello,

I am doing some troubleshooting and I noticed that my sources.list file does not have any information. Should it have something? I use the following command: root@kali:/etc/apt# less sources.list. I notice on Kali's help pages they mention not to modify this list, why? I am hoping I am doing something incorrect but I also tried vi but received the same nothing but "~" all across the left side of the window.

I am using Kali 2.0 64 bit on Virtual Box and a Win 7 laptop.

Thanks again,
R

If you do not have any lines in your sources.list file you should add the following:

Code:

---

deb http://http.kali.org/kali sana main non-free contrib
deb http://security.kali.org/kali-security sana/updates main contrib non-free
