 This library provides implementaion of WebDav and SMB/CIFS (incomplete) and local files.
 
 All functions are async calls and it wont block your main thread.
 
+Local and WebDAV providers are fully tested and can be used in production environment.
+
 ## Features
 
-- [x] **LocalFileProvider** a wrapper for `NSFileManager` with some additions like searching and reading a portion of file
-- [x] **WebDAVFileProvider** WebDAV protocol is usual file transmission system on Macs
-- [ ] **SMBFileProvider** SMB/CIFS and SMB2/3 are file and printer sharing protocol which is originated from IBM & Microsoft and SMB2/3 is now replacing AFP protocol on MacOS. I Implemented data types and some basic functions but *main interface is not implemented yet!*
-- [ ] **DropboxFileProvider**

+#### Controlling file operations
+
+You can also implement `FileOperationDelegate` protocol to control behaviour of file operation (copy, move/rename, remove and linking), and decide which files should be removed for example and which won't.

+
+`fileProvider:shouldProceedAfterError:operation:` will be called if an error occured during file operations. Return `true` if you want to continue operation on next files or `false` if you want stop operation further. Default value is false if you don't implement delegate.

 ### Monitoring FIle Changes
 
+You can monitor updates in some file system (Local and SMB2), there is three methods in supporting provider you can use to register a handler, to unregister and to check whether it's being monitored or not. It's useful to find out when new files added or removed from directory and update user interface. The handler will be dispatched to main threads to avoid UI bugs with a 0.25 sec delay.

+* **Please note** in LocalFileProvider it will also monitor changes in subfolders. This behaviour can varies according to file system specification.
