This skill is designed to help you remember where you put your stuff. You can tell it where your stuff is and after you inevitably forget it, you can just ask Alexa. Unfortunately this is setup for a pretty strict input structure. For making an entry say something like "My/The/... stuff is/are in/at/under/... location", and for getting reminded the command structure is "where is/are my/the/... stuff". You can also delete entries. I hope this skill helps somebody.
