Minecraft wee config?

I use plotsquared and wanted to know where the edges of the plots are stored (where in the config?). Because I have created my own way but the edge is mixed.

Actually, you should be able to change this when creating the plot world. So look at the command. You should be able to change everything (from which blocks the plots are made, how big they are, with which blocks the path is built, what the edge of the plots is, etc.)
