 Icons
 -----
-All project icons are kept in `jsapp/svg-icons/`. Adding new icon requires adding new `svg` file here and regenerating icons with `npm run generate-icons`. Filenames are used for icon font classnames, e.g. `.k-icon-arrow-last` for `arrow-last.svg` (please use kebab-case). You can see all available icons by running `npm run show-icons` - it will open a list in your browser.
