By default, the provider uses treemacs, so make sure that you have that
in your load path. If you wish to use all-the-icons icons instead, set helm-icons-provider
to 'all-the-icons. Or if you wish to use nerd-icons icons (which is usable in terminal,
more information here), set helm-icons-provider to 'nerd-icons.
Make sure that you have helm and your icon provider installed, clone the repo
and put it on your path. Make sure that the enable call is performed before
loading helm.
(helm-icons-enable)If you use all-the-icons and you haven’t installed the fonts before, you will be prompted to do so.
The following are images showing how it looks like when using with nerd-icons. Notice that
the second is in konsole.
