 ## How it works
 
 * it will compute a hash of each file present in the directory structure (it works recursively).
-* if previously computed `legdur.db` exists it will compare the current state of the world to the one represented by `legdur.db` and output any differences. Only files that changed or got deleted get printed out, additions are not.
+* if previously computed `legdur.db` exists it will compare the current state of the world to the one represented by `legdur.db` and output any differences. Only files that changed or got deleted get printed out, additions or file moves anywhere within the directory are not.
 * it will move the current `legdur.db` to `legdur.old` and write the new state of the world to a new `legdur.db`
