Looking for best/most efficient way to add emulators to Playnite on my MSI Claw 8 ai

Just got a Claw 8 and have nothing but playnite installed with a few of my steam games loaded up in it. I have no emulation experience on pc, how to download emulators, roms, and where to put them, or actually how to even play the roms. Looking for some advice on what would be most efficient way to get them installed then imported into Playnite. I've read installing all Emulators separately, then Roms, and importing 1 by 1. I've also read using Emudeck then importing that into Playnite. Wanting to install all the way from NES-PS3. Any help would be greatly appreciated!!
