 # Oracle APEX Region Type Plugin: dhtmlxGantt
 
-* Based on [dhtmlxGantt][2] ([docs][3]) library (v7.0.11)
-  * This is the GPLv2 version of the library with a reduced set of functions
-    * [Compare the free and the Pro version][compare]
-  * If you need all functionality you can buy the Pro version and copy the Pro files into the plugin
-  * I was asked to create this plugin and I have nothing to do with the company DHTMLX, so please do not complain ;-)
-* Minimum supported APEX version is 5.1
-* Features of the APEX integration:
-  * Data can be delivered as XML (string) or JSON (string or object)
-    * For the XML format there is an own parser integrated to support easy SQL queries - see example below
-  * The plugin delivers sample data, if no query is defined
-  * There are five events available to react on chart actions: Task Create, Task Double Click, Task Drag (change of progress, start date, duration), Link Create, Link Double Click
-  * In the region attributes you can configure some aspects of the Gantt chart - for an example the height, the skin, the UI language (30 different delivered by the vendor); There is also the possibility to place custom before and after initialization JavaScript code
-  * Everything else can be done with the extensive JavaScript API available from DHTMLX - please refer to the [docs][3]

+- Based on [DHTMLX Gantt](https://dhtmlx.com/docs/products/dhtmlxGantt/) library v7.0.11 ([docs](http://docs.dhtmlx.com/gantt/))
+- This is the GPLv2 version of the library with a reduced set of functions - [Compare the free and the Pro version](https://docs.dhtmlx.com/gantt/desktop__editions_comparison.html)

+## You need to understand this
+
+- The whole idea of the plug-in ist to integrate the Gantt JavaScript library and to expose relevant events to be able to use standard APEX modal dialogs to edit the tasks and links
+- The downside of this is, that you need to work with the event data to open your modal dialogs and that you need to prepare your URLs somewhere
+- You can prepare the edit URLs beforehand in the region SQL
+- When you change data by interacting with the graph you need to prepare the URL with a dynamic action
+- It is highly recommendet to install the demo app and inspect the implementation details:
+  - Open the [online demo app](https://apex.oracle.com/pls/apex/ogobrecht/r/playground/gantt-chart)
+  - Download it as it is (top right navigation menu, under the question mark)
+  - Install it in your own APEX instance or [apex.oracle.com](https://apex.oracle.com/), if your instance has not the same version as [apex.oracle.com](https://apex.oracle.com/)
 
 ## How To Use
 
-### The Recommended Way
-
-1. Download the [latest version][1]
-2. Go to subdirectory `plugin/demo-objects` for a demo app including supporting objects 
-3. Run the demo app and inspect, how it was implemented
-
-Notes: Demo app is for APEX 20.2, sorry... try it on apex.oracle.com. Plug-in is still for APEX 5.1.4+ (downgrade was made with a diff tool comparing with an old plug-in version).
