No need to guess it, i will add the problem to the readme.

In short, the problem was, that we always had like 10 bottles of ketchup in our basement, because we never knew that we still have this many... So we ended up buying the stuff we already had and still forgot the things we needed. So we had to go again.

This way, you can easily VPN into your home network and search for the things you need and not the ones from which you still have enough.
