 ### Description
 
-When run, the Watcher scans for `jcr_root/*` folders within the `path_to_watch` (dot-prefixed and "target" folders are omitted). This may take a while depending on the size. After the scan is done, file system changes inside those folders are detected and deployed to AEM instance(s) as a package.
+The Watcher uses Node's `fs.watch()` function to watch over directory changes recursively. For Windows and OSX the `recursive` option is used, which significantly improves the performance. Any changes inside `jcr_root/*` folders are detected and deployed to AEM instance(s) as a package.
 
-Update interval is the time the Pusher waits for file changes changes before the package is created. In case of multiple file changes (e.g. switching between code branches), creating a new package per file should be avoided and instead, all changes should be pushed in one go. Lowering the value decreases the delay for a single file change but may increase the delay for multiple file changes. If you are unsure, please leave the default value.
