You mean how do I use it for streaming? That changed over the years and I haven't been using it for streaming the last months due to circumstances. But if you are looking for suggestions, then I would point you to DietPi as OS and Kodi as media center. You can configure it to dierctly boot into Kodi, and if you use NewPipe as YouTube client on your smartphone, you also get a convenient option to play videos on Kodi. Plus you can stream any file you have on your PC or smartphone. To stream from Linux I used idok, but there could be others.
