[TUTORIAL] How to create a country from scratch

Really it depending what you want to create. A basic version would be as follows;

• create a copy of the .cvp file, create the region ID and all of it's stats
• Use the mapeditor to give land to that region (must match region ID). This makes a .mapx, and .oof file
• create a copy of a RegionINCL file, add the region to the list
• create a .scenario file that uses your custom .cvp, .RegionINCL, .mapx and .oof file. Specify a new savegame file
• create a cache for your new .scenario file

If you are adjusting exiting combinations, that's easier. If you want to give them starting inventory of units and set up relations with other regions, there are more steps.

The file names might be different, but the instructions should be the same for SR2020. The SupremeWiki information usually says if something is for a specific version only.
