-## draw.io project sources
+About
+-----
+[draw.io](https://www.draw.io) is an online diagramming web site that delivers the source in this project.
 
-draw.io comprises three parts:
+draw.io uses the [mxGraph library](https://github.com/jgraph/mxgraph) as the base of the stack, with the [GraphEditor example](https://github.com/jgraph/mxgraph/tree/master/javascript/examples/grapheditor) from mxGraph as the base of the application part. The mxGraph library build used is stored under /etc/mxgraph/mxClient.js.
 
-1. The static web content under the `war/` directory.
-2. The open, save, embed, proxy and iconfinder servlets as one servlet war. These are located under `src/com/mxgraph/online/`.
-3. The image export servlet. This is located under `etc/imageexport/`.
+License
+-------
+draw.io is dual licensed under either the GPL v3 or the [mxGraph Commerical License](https://www.jgraph.com/Licenses/JGraph_Software_Licence.pdf). To use the commercial license, you must license from [JGraph](https://www.jgraph.com/purchase-mxgraph.html) for payment.
 
-Prior to invoking any builds, search `war/index.html` for *CUSTOM_PARAMETERS*. The image *EXPORT_URL* is the most important variable to change. 
-Without that the export to image will use our server, which somewhat defeats the point of hosting it. The servlet is mapped to *export* and the default name 
-of the war is *Imageexport* so `/Imageexport/export` is the value if you deploy that war as-is and the servlet engine is on the root of the domain.
+Running
+-------
+The simplest way to run draw.io initially is to fork this project, [publish the master branch to Github pages](https://help.github.com/categories/github-pages-basics/) and the [pages sites]https://jgraph.github.io/draw.io/war/index.html) will have the full editor functionality (sans the integrations).
 
-* `/etc/build/build.xml` is the ant build file for the main war. Invoking `ant war` will generate `build/draw.war`.
+Supported Browsers
+------------------
+draw.io supports IE 9+, Chrome 30+, Firefox 31+, Safari versions actively patched by Apple (6.2.x, 7.1.x, 8.0.x and 9.x at time of writing), Opera 20+, Native Android browser 5.x+, the default browser in the current and previous major iOS versions (e.g. 9.x and 8.x) and Edge 20+.
 
-* `/etc/imagexport/build.xml` is the ant build file for the image export war. Invoking `ant war` will generate `etc/imageexport/imageexport.war`.
-
-Deploy these wars on a servlet engine and navigate to the location of the first war, you will get the draw.io application.

-## Licensing
-
-The underlying mxGraph library is licensed to you either the [CCNC](http://creativecommons.org/licenses/by-nc-sa/3.0/) or the 
-[mxGraph commercial license](http://www.jgraph.com/mxlicense.html) (if you're a paying customer). Please understand that we make 
-a living selling the mxGraph library commercially, we need to avoid draw.io being 
-used freely where mxGraph would previously have been sold.
-
-The source to draw.io itself is Apache 2.0 licensed (or mxGraph Commercial License), but obviously the mxGraph license dominates this for commercial 
-purposes.
-
-We separate between developing against the mxGraph API and just deploying draw.io for general usage. Thus, we make exceptions to the CCNC license 
-if you want to take draw.io as-is and deploy it for your own use (note this only affects commercial users). Below, we will build up a list of alterations 
-you can make to draw.io without being subject to the mxGraph commercial license (note this only affects commercial users):
-
-* You can alter draw.io paths so that the functionality works correctly in your deployment environment
-
-* You can add and remove menu options and library stencil sets to/from the UI
-
-If you require more exceptions, please add to issue tracker.
