 PHP wrapper for `smbclient` and [`libsmbclient-php`](https://github.com/eduardok/libsmbclient-php)
 
 ```
 
 **Note**: write() will truncate your file to 0bytes. You may open a writeable stream with append() which will point
-the cursor to the end of the file or create it if it does not exists yet. (append() is only compatible with libsmbclient-php)
+the cursor to the end of the file or create it if it does not exist yet. (append() is only compatible with libsmbclient-php)
 ```php
 $fh = $share->append('test.txt');
 fwrite($fh, 'bar');
 $serverFactory = new ServerFactory($options);
 ```
 
+### Setting protocol version
+
+```php
+$options = new Options();
+$options->setMinProtocol(IOptions::PROTOCOL_SMB2);
+$options->setMaxProtocol(IOptions::PROTOCOL_SMB3);
+$serverFactory = new ServerFactory($options);
+```
+
+Note, setting the protocol version is not supported with php-smbclient version 1.0.1 or lower.
+
 ### Customizing system integration
 
 The `smbclient` backend needs to get various information about the system it's running on to function
 such as the paths of various binaries or the system timezone.
-While the default logic for getting this information should work on most systems, it possible to customize this behaviour.
+While the default logic for getting this information should work on most systems, it is possible to customize this behaviour.
 
 In order to customize the integration you provide a custom implementation of `ITimezoneProvider` and/or `ISystem` and pass them as arguments to the `ServerFactory`.
