Kali Nethunter Not Working

Im trying to install kali nethunter in termux but the file isnt showing up any where. Heres what i did so far.

$ls

kali-nethunterstorage

$cd Nethunter-In-Termux

bash: cd: Nethunter-In-Termux: No such file or directory

$cd kali-nethunter

$ls

nethunter-fs

nethunter-installer

version.txt

$chmod +x nethunter-installer

$./nethunter-installer

bash:./nethunter-installer: Is a directory

What do I do to install it when all i have are is the installer and what ever nethunter-fs is. Theres no kalinethunter file like all the tutorial videos show and now im stuck. Please help.
