+#Map Merger#
 Before any change to a map, it is good to use the Map Merger tools. In a nutshell, it rewrites the map to minimize differences between different versions of the map (DreamMakers map editor rewrites a lot of the tile keys). This makes the git diff between different map changes much smaller. More recently a new way of laying out the map was invented by Remie, called TGM, this helps to further reduce conflicts in the map files.

+#Common pitfalls#
+Open the map in dreameditor before committing the results of the mapmerger - this can cause dreameditor to resave the map back to
+dmm, if you're having issues with your map getting stuck in dmm mode, try comitting and pushing the mapmerger changes before 
+reopening in dreameditor.
