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.
A development guide is being started on the GitHub project wiki. There is a [draw.io](http://stackoverflow.com/questions/tagged/draw.io) tag on Stack Overflow currently, please make sure any questions adhere to their guidelines for question.
The [mxGraph documentation](https://jgraph.github.io/mxgraph/) provides a lot of the docs for the bottom part of the stack. There is an [mxgraph tag on SO](http://stackoverflow.com/questions/tagged/mxgraph).
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).
The full packaged .war of the client and servlets is built when the project is tagged and available on the [releases page](https://github.com/jgraph/draw.io/releases).
draw.io supports IE 11, Chrome 32+, Firefox 38+, Safari 7.1.x, 8.0.x, 9.1.x and 10.0.x, Opera 20+, Native Android browser 5.1.x+, the default browser in the current and previous major iOS versions (e.g. 10.x and 9.x) and Edge 23+.
