 * Notes
+
+** project.godot
+- best not to edit
+- this file has to be there for godot to recognize the folder as a godot project
+
+** import files
+- for every file imported, there will be a file with a similae name only the extension .import
+- these import files contain metadata used by godot
+
+*** resources
+- are data containers
+- have unique ids
+
+*** why does this matter
+- if an import isn't working, you can open the import file and see if something needs fixing
