Ground Zero ROMs are not shipped rooted. Flash your favorite root apps like Magisk/SuperSU or any other. After flashing, your device may boot twice before boot animation, don't worry it'll be fine after that.
Substratum support is there as long as you have root and latest Substratum app. Some themes may have a little catching up to do, have fun testing them!
If you have any issues, grab a log after a clean flash, upload and link here please. Add steps to reproduce the issue in your post.
Do not report issues dirty flashing this over some unofficial build or with some kernel flashed.
Logcat Extreme app is great as you can choose to start recording a log just before reproducing an error and stop recording just after so you log just the part you need.
Xposed is not supported here, if you want to run it and have issues, try an Xposed thread for support and bug reports here only welcome with a clean install with no Xposed present.
Selinux is permissive for now.
Make sure to state which rom you are running when asking for support
