free5gc/NFs folder is empty

I found that all subfolders in the ‘NFs’ folder under free5gc are empty.What should I do

Hi, ropz
you can use the following command to clone the repo
git clone --recursive https://github.com/free5gc/free5gc.git
make sure git is installed and no SSL verify error messages popping up.
If that still doesn’t work, you can download the repo as a zip.

notes. refer to this page for installation steps.
