Province borders are not a consideration for Dominions2 as they were for Dominions - PPP, because the map editing system has been (fortunately) completely revamped.

Dom2 recognizes white (RGB 255, 255, 255) pixels as provinces. Every single one of them. If you've got two adjacent white pixels, they will be two different provinces, and if you accidentally get two pixels like that and don't notice, you'll get a big headache in the map editor (been there and done that...).

Any borders you draw on the map are completely ignored by the game, they are there only to let the players know where the borders supposedly run. The game operates on white pixels (which are presumably placed in the center of the province.

Province numbering order moves line by line from bottom right to upper left corner and the pixel location determines the province number.

Now, what that passage in the mapedit.pdf means is that you must assign terrain and neighboring provinces in the map editor before you start the advanced editing that needs to be done with a text editor. That "Click in all terrain and borders" should have been formulated as "Assign terrain and neighboring provinces".

Hope this helps.
