Dark Material Theme for Wallabag
Based on Theme created by Danilow (@modos189) Alexandr http://modos189.ru/
Used framework http://materializecss.com/

Either clone into your wallabag install's root folder from branch 2.3.3
or 2.3.4
or download a release and copy the contents of the folder into wallabag's root.
Lastly run php bin/console cache:clear -e prod
to clear the cache as part of the install process.
