 # exifmv
 
+Moves images into a folder hierarchy based on EXIF tags.
+
+Currently the hierarchy is hard-wired into the tool as this suits my needs.
+In the future this should be configured by a human-readable string supporting regular expressions etc.
+
+For now the built-in string is this:
+`{destination}/{year}/{month}/{day}/{filename}.{extension   }`
+
+So if you have an image shot on Nov. 22. 2019 named Foo1234.ARW it will end up as this folder hierarchy:
+`2019/11/22/foo1234.arw`.
+
