+### Automatically adjust textarea width/height based on user input.
+#### Non-sucking version, still works great and used by a lot of people with no issues!
+
+
+The only reason I wrote this jQuery plugin is that other plugins suck. They are wide-spread, but outdated and buggy.
+
+Advantages of jquery.ns-autogrow:
+
+* Grows vertically, horizontally or both
+* Correctly handles 2 or more spaces
+* Copies more css and font styles to shadow div
+* Correctly handles long words on one line
+* Flickering can be disabled on Enter
+* Doesn't add more than one handler to textarea
+* Handles textarea scrollbar if any
+* Improved support of special characters
+
+## Download
+Run one of these commands in your bash according to your needs.
+
+`git clone https://github.com/ro31337/jquery.ns-autogrow.git`
+
+`bower install jquery.ns-autogrow`
+
+`npm install jquery.ns-autogrow`
+
+Or download the latest version from the [releases](https://github.com/ro31337/jquery.ns-autogrow/releases) page.
+
+### Options
+
+You can provide multiple options to autogrow like:
+
+```
+  $('.example2 textarea').autogrow({vertical: true, horizontal: false});
+```
+
+List of options:
+
+Option | Description
+-------|------------
+vertical | (true/false) - Enable/Disable vertical autogrow (true by default)
+horizontal | (true/false) - Enable/Disable horizontal autogrow (true by default)
+postGrowCallback | Post grow callback. Executes after dimensions of textarea have been adjusted.
+flickering | (true/false) - Enable/Disable flickering. If flickering is disabled, extra line will be added to textarea. Flickering is _enabled_ by default.
+
+There are few more options reserved for debugging purposes. All debugging options start with `debug` prefix:
+
+Option | Description
+-------|------------
+debugx | X position of shadow element (-10000 by default)
+debugy | Y position of shadow element (-10000 by default)
+debugcolor | Color of shadow element (yellow by default)
+
