Great article, I have been looking into Pleroma for awhile now and this tutorial is great. Mr Doerings write up is amazing and for someone that only knows so much it helped me understand some whys, and allowed me to fix things. All in all this ended up not working out for me though, I got stuck time and time again. I finally got Pleroma running on DigitalOcean, and currently working on getting it on my raspberry pi. Will come back to this, check out yunohost, there is a user created app you can use it via pleroma
