Most users of HA have integrated multiple, dozens or even hundreds of different devices. It would be very helpful if there would be a possibility to upload the related manuals for each device to directly offer the HA supervisor the manual for downloading while working in home assistant and also offering the users / family members / guests an overview of all manuals in a special room of the house (kitchen, garden, living room etc) so they have access to the electronic manuals. Currently I am embedding the manuals via an iframe for each room from my personal website and it works great but integrating this into HA would make much more sense.
