M3U Setup Help

I just downloaded Kodi to view the IPTV subscription I recently purchased. I’ve found a bunch guides on how to set up a m3u stream, but all seem to be for an older version and don’t even remotely apply to the latest version of Kodi (as the interface is now completely different than it was before).

I’ve tried adding my playlist through multiple menu options and did an add-on search for the IPTV Simple plug-in, but everything’s come up short. Can someone give me a brief walkthrough on how to add my stream?
