+MAPPER QUICK GUDE
+Looking to add new overmap POI's with as little code knowledge as possible? Here's the vital stuff:
+-Maps are stored in /datum/map_template/dynamic_overmap templates, you will need to make one template per POI. Code automagically handles adding templates to the overmap.
+-The "name" variable must be unique.
+-The "mappath" variable must be the file path of your map file. Store maps in "modular_chomp/maps/overmap/space_pois."
+-The "block_size" variable is the tile size of your map's LARGEST dimension. Code may break horribly if you do not set this correctly.
+	-If your map is 60 tiles by 45 tiles, the block_size should be 60.
+-ADD YOUR MAP(s) TO THE #include LIST BELOW. This lets github catch POI's breaking in the future.
+-Keep templates alphebetical.
+-Include the map dimensions in the map file name.
+
+Less important
+-"scanner_desc" is the information presented to players upon scanning the POI. You should probably fill this out but it's not necessary for POI spawning.
+-"poi_icon" is the icon_state used when the POI is first scanned.
+-"active_icon" is the icon_state used when the POI is loaded into the game.
+-POI icons use "icons/obj/overmap.dmi" by default. Using other .dmi files is not currently supported but would be easy to code if desired.
+-"poi_color" colors the overmap object when set, does nothing when null. Uses hexadecimal color codes.
+-Most POI spawning code is in dynamic_sector.dm, if you're looking for it.

 // This causes PoI maps to get 'checked' and compiled, when undergoing a unit test.
 // This is so CI can validate PoIs, and ensure future changes don't break PoIs, as PoIs are loaded at runtime and the compiler can't catch errors.
 // When adding a new PoI, please add it to this list.
