I've never been able to get Josm to work for me. I've looked at tutorials and everything. I tried to make sense of it and make it work for around a year in the past but to no avail. I can't even do that cuz my laptop has since broken.
There are some differences, so it's not exact copying.
I dunno if it's against rules or not, still. Probably is.
Because I had to look at it before a good 3 minutes to realize that it was similar.
