New user needs complete setup tutorial for walk-in phone order restaurant

[yummy]

I followed this tutorial and created two entities to show on POS screen however only one showed up.

Help! Restaurant opens next week and I have no idea what to do!

Hello, This tutorial is for the new restaurant owner, who is trying to open their first restaurant next week, who told everyone the store would have been open a month ago, for whom everything has gone wrong and they are almost bankrupt before making their first sale, who knows almost nothing about POS (point-of-sale = computer-as-cash-register), who has a thousand other things they are working 20 hours a day, and doesn’t know where to start with SambaPOS. The tutorial is written from the perspe…

I than closed out the pos and restarted. Now when I click on the POS tab it shows the order screen at once. It does not show any entities now.

I uninstalled the program thinking I will start over but all the settings remained after reinstall.

How can I fix this? or how can I completely uninstall the POS and start from scratch again?

Thanks
