Question with Aircrack Ng with Kali

I am using aircrack-ng on kali and this linkhttps://null-byte.wonderhowto.com/how-to/hack-wi-fi-cracking-wpa2-psk-passwords-using-aircrack-ng-0148366/ is based on backtrack so the wordlist is different. Do I need to download a new wordlist or is there already a wordlist that i can use?

also could you tell me how to write the commands?
