Good job! I'm probably going to use this. Would love to have my collection accessible from mobile. A small "nit". Would be great to have non-docker installation instructions readily available.
I did not go through minimum requirements but I have a LAMP stack running radius for a small shop and so far, runs happily on an RPi 2 featuring 1 GB of RAM. I have daily backups and everything required to spin up a clown if the SD card becomes faulty.
