So you wanna run a radio station?
This repo serves as the basis of radio.smplrtrn.one or smplrtrn.radio or ddtdt.radio ...
However, it owes almost everything to icecast2, youtube-dl, liquidsoap and James Hunt's neat little dockerization of those and a smart vue UX.
If your not familiar with the concepts of any of these, head over to James' blog series on containerization (0-4) and grow as you play)))
