Synology How to Activate Dark Mode in Portainer

It may come as a surprise to some users, but the Dark Mode feature has been available in Portainer starting with version 2.9.0. Dark Mode has been one of the most requested functions by Portainer users. However, many users are still not aware of it and for this reason, today, I wanted to get back to this topic and explain to those who have Portainer installed on their Synology NAS and are not yet up to date with the new features available how to activate the Dark Mode option.

What is Portainer? Portainer is a really awesome web UI for Docker. Portainer is a lightweight management UI which allows you to easily manage your different Docker environments (Docker hosts or Swarm clusters). Portainer is meant to be as simple to deploy as it is to use thanks to its user-friendly interface. Those who have had the pleasure of trying Portainer have left Synology’s web UI behind and focused on the new user friendly interface offered by Portainer.
