+   Font Awesome Free License
+   -------------------------
+
+   Font Awesome Free is free, open source, and GPL friendly. You can use it for
+   commercial projects, open source projects, or really almost whatever you want.
+   Full Font Awesome Free license: https://fontawesome.com/license.
+
+   # Icons: CC BY 4.0 License (https://creativecommons.org/licenses/by/4.0/)
+   In the Font Awesome Free download, the CC BY 4.0 license applies to all icons
+   packaged as SVG and JS file types.
+
+   # Fonts: SIL OFL 1.1 License (https://scripts.sil.org/OFL)
+   In the Font Awesome Free download, the SIL OLF license applies to all icons
+   packaged as web and desktop font files.
+
+   # Code: MIT License (https://opensource.org/licenses/MIT)
+   In the Font Awesome Free download, the MIT license applies to all non-font and
+   non-icon files.
+
+   # Attribution
+   Attribution is required by MIT, SIL OLF, and CC BY licenses. Downloaded Font
+   Awesome Free files already contain embedded comments with sufficient
+   attribution, so you shouldn't need to do anything additional when using these
+   files normally.
+
+   We've kept attribution comments terse, so we ask that you do not actively work
+   to remove them from files, especially code. They're a great way for folks to
+   learn about Font Awesome.

+   trademarks does not indicate endorsement of the trademark holder by Font
+   Awesome, nor vice versa. **Please do not use brand logos for any purpose except
