 Django Admin Interface
 ----------------------
 As this is a Django project, you may find the admin panel at `<kpi base url>/admin` useful, e.g. to configure user accounts or log in as other users without knowing their passwords. You must use a superuser account to access the admin panel.

+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.
