env file

I am still trying to figure out where to put the env file. I put the file I have in the directory. I use phoneinfoga scan -n +4176418xxxx --env-file=.env.local but nothing happens. all I see is 2 scanners. when i run numverify by itself, it works that way. Does it matter what you name the env file? Where exactly do i have to put it in order for it to work?
