Super easy to set up, and so then you’ll have your own little app for you to use, and you can share it if you want to.
But WARNING! If you share it too much and it goes viral, it becomes overloaded and people abuse / attack it. So share it your own peril! Personally, I won’t share my own maps I made, but I’m happy (as well as the originator), to share the instructions of how to make your own.
