 to synchronize the folder /bar (of the container named bar) with the local folder foo/.
 
-Note that: The options -a -u --delete respectively, allow copying of files to the target directory,

-directory and deleting files that are in the destination directory but not in the source directory.
+By default `sync-mht` will only show a statistic about the difference between the source and
+destination directories.  The options `--add`, `--update` and `--delete` respectively allow
+copying of files to the target directory, updating files that are already in the target directory -
+not matching the contents in the source directory and deleting files that are in the destination
+directory but not in the source directory.
 
 ## Setup
 Installing the latest release of sync-mht with [stack](https://github.com/commercialhaskell/stack):
