This repository contains a set of free icons, which can be used on CODESYS Forge.
We don't encourage you to use them in other contexts, but you can do that if you respect the licenses of the copyrights owner.
Font Awesome is a very nice and widely used project to provide free, scalable icons in form of font files. But they also provide their icons in form of SVG files.
The fonts, which are found in this repository are converted from the SVG files to PNG, with some shadow added to it, so that they are usable on light and dark backgrounds.
