How to do Adaptive Bitrate Streaming (ABR) in HLS?

Hey Guys, Is there an example of how to do adaptive bit rate streaming with Evostream? I can generate HLS fragments and m3u8 playlist quite easily, but they are all at a single bitrate. Basically, I turned on autoHLS and played out a stream to Evostream from ffmpeg. What I am looking for, is:

I play out a stream to EvoStream. Evostream transcodes the incoming stream into multiple renditions (at various bitrates) EvoStream generates fragments of the multiple renditions Evostream generates the correct m3u8 playlists for a player to perform ABR on the multiple transcodes

Thanks
