Can anyone help me install Stock Rom for HTC One Mini?

[HTCOneMiniUser]

Hey everyone, I tried to root my HTC One Mini and when I tried installing supersu it didn;t work. I have my bootloader unlocked and have latest TWRP. I wiped the phone in TWRP to try to fix the problem with the supersu installation and accidently deleted the Android OS. I have been trying to install a custom stock rom but I'm not rooted. I have been searching for a stock rom but am having trouble. If anyone can find a stock rom or a RUU that will work that will be great. Here is the information for my phone, (It's an AT&T and in the US by the way)
