+Before installing on a Synology NAS, you will need to follow the instructions in the Plex support article [How to add Plex’s package signing public key to Synology NAS Package Center](https://support.plex.tv/articles/205165858-how-to-add-plex-s-package-signing-public-key-to-synology-nas-package-center/).
