 # IFM - improved file manager
 ## about
-This is a simple filemanager. It is a single file solution which uses HTML5, CSS3, JavaScript and PHP. It works like a client-server system where HTML5/CSS3/JavaScript is the client part and the PHP API acts as the server, which reduces the traffic significant.
+The IFM is a web-based filemanager, which comes as a single file solution using HTML5, CSS3, JavaScript and PHP.

 The IFM uses the following resources:
 * [ACE Editor](https://ace.c9.io)
 * [Bootstrap v3](https://getbootstrap.com)
-* [jQuery](https://jquery.com)
 * custom icon set generated with [Fontello](http://fontello.com/)
+* [jQuery](https://jquery.com)
+* [Mustache](https://mustache.github.io/)

+## features
+* create/edit files and directories
+* copy/move files and directories
+* download files and directories
+* upload files directly or via URL
+* extract zip archives
+* change permissions
+* image preview

 Currently there are no known issues. If you find any flaws please let me know.

 ## security information
-The IFM was developed with the assumption that the highest level of operation is the scripts base location. So it is neither possible to nagivate nor to use any API function in a level above the script root.
-
-It is highly recommended to restrict access to the script e.g. using a basic authentication.
+By default, the IFM is locked to it's own directory, so you are not able to go above. You can change that by setting the $root_dir in the scripts configuration.
