We recommend first and foremost open source software such as [Inkscape](https://inkscape.org/en/) or [Pencil](http://pencil.evolus.vn/) (a [complete list](http://opensourcedesign.net/resources/#design-tools)), but at the same time we know most of them are behind popular software for web design workflows. You can use any design software that's available to you. Just make sure to include editable exports (SVG, PDF, EPS) along with your source files.
