-The <b>plain</b> and <b>line</b> versions (with or without wordmark) are designed to be available in the final icon font. This means they need to stay as simple as possible (one color and ensure that the paths are united before to export to svg). You can use a service like <a href="https://compressor.io/">compressor</a> or <a href="https://petercollingridge.appspot.com/svg-editor">SVG Editor</a> in order to optimize the svg file.

 Some icons are really simple (like the Apple one), so the original version can be used as the plain version and as the icon font. In this case, you'll only need to make only one of the version (either "original" or "plain"). You can then add an alias in the <code>devicon.json</code> so they can be found with either the "original" or "plain" naming convention.
