[HELP] Iris Manager Inexperience

I never actually used Iris Backup Manager, but only read changelogs of a few releases. I'm having trouble setting it up properly on 4.30 Rebug CFW.

After installation of the latest version where do I put the other extracted material (payloads & etc.) at within /dev_hdd0/game/IMANAGER4 using multiMAN?

If able can someone explain it to me in a step process?
