+## Creating icons
+
+- Most icons come from the [`fontawesome5`](https://ctan.org/pkg/fontawesome5?lang=en) TeX package \[[with documentation](http://mirrors.ctan.org/fonts/fontawesome5/doc/fontawesome5.pdf)\].
+- Some are custom made (those not in `fontawesome5`).
+  - Find an open-licensed SVG vector on <https://www.svgrepo.com>
+  - Ensure whitespace is cropped from the SVG `viewBox`: <https://svgcrop.com/>
+  - Minify and strip the resulting SVG: <https://jakearchibald.github.io/svgomg/>
+  - Convert svg to png: `inkscape --export-type png -w 1024 --export-filename /path/to/new.png /path/to/my.svg`
