Help Me Please AI 8 with UR 22

hi… can someone help me please, how on earth do you record you own guitar bass and vocals ? in easy to understand language. in steps…its cracking me up, i managed to record on Reaper with Line 6 Pod Studio, easy enough then i thought i would get a better interface, just made things more difficult for myself… and its consuming me…

basically what do you select to record proper guitars not VST?
