+This is collection of SVG icons created by various authors, released under various open source licenses. Some collections require attribution when used for commercial purposes. See [collections.md](./collections.md) for list of collections and their licenses.
 
 All SVG icons have been cleaned up. Content has been optimized, colors for monotone icons have been replaced with currentColor, ready to be inserted in HTML. Tools used for creating this collection are available on [Iconify GitHub repository](https://github.com/iconify), more specifically [@iconify/tools](https://github.com/iconify/tools). You can use it to create your own JSON packages from custom icon sets.

 Width or height might be missing. If icon does not have width or height, use default width or height from root object.
 rotate, hFlip and vFlip are all optional.
 
 Optional "aliases" object contains list of aliases for icons. Format is similar to "icons" object, with additional property "parent" that points to parent icon. Any other properties overwrite properties of parent icon.
