Help - New to streaming and Zen Innuos

For reasons I won’t bore you with I have found myself very late in life moving my digital music from a CD player to streaming ( my age is such that a Garrard SP25 Mk3 was my first turntable). As such I am a complete novice and decidedly non-tech. I have a Zen Innuos Mini Mk3 which I’m using both as a streamer and server pending the delivery of a Naim streamer that is taking a long time to appear as Naim are having parts availability problems. I’m looking for links to useful articles etc to familiarise myself with the subject and the Innuos manual is VERY basic. Anything that might help my lack of knowledge would be great. I’m currently using the iPeng app on my iPad but understand the new Innuos app for the Zen mini 3 should be working on 28 July. I’m guessing that ultimately I’ll use the Naim app. As well as my ripped CDs I use the Tidal app although it’s functionality via iPeng isn’t great and also internet radio stations seem limited. I’m of an age that `I was used to kit coming with extensive printed manuals but those days are long gone. Anything I read needs to be understandable to non-tech novices. Sorry to ramble on but this has been a big step to take although I still have my vinyl to fall back on as well.
