This project was forked from https://github.com/spothq/cryptocurrency-icons & is now used to generate icons & react components for BitGo apps.
$ npm install cryptocurrency-icons
You can then import the icons from ./node_modules/cryptocurrency-icons, for example ./node_modules/cryptocurrency-icons/svg/color/kmd.svg.
There's also a manifest.json file included in the package with a list of the currency symbol, the name of the icons and the associated colors.
After adding the new icon to the /svg/color directory, generate the corresponding React component for it:
$ npm run generate
and include both in the commit.
