 mxGraph is a fully client side JavaScript diagramming library that uses SVG and HTML for rendering. [draw.io](https://www.draw.io) is an example that extends the functionality of this library. The [sources to draw.io](https://github.com/jgraph/draw.io) are also available.
 
+Note this is the release repo. The development repo is on [Bitbucket](https://bitbucket.org/jgraph/mxgraph2).

 If you want to build something like draw.io, [GraphEditor](https://jgraph.github.io/mxgraph/javascript/examples/grapheditor/www/index.html) is the best example to use as a base.
 
 The npm build is [here](https://www.npmjs.com/package/mxgraph).
