It takes years to learn programming. Even people with years of experience may not be able to jump in on github and start building. That said your question about on-boarding is a good one if there was an expectation of some minimum pre-requisites that people should have.

There is already abundent information on coding for nostr. It is not that hard, but takes time. Try searching youtube for 'programming for nostr'.

One place to start is reading the code for "nostr tools" that are in type script ( https://github.com/nbd-wtf/nostr-tools ) and I know I saw some in rust also. Is the nostr development kit (NDK) available in different languages? JeffG did a video on the NDK about a month ago ( https://www.youtube.com/watch?v=Xzwx21oq8Hk )

Maybe as a study aid, some of the Developers could point new builders to a very simple client or early fork that would be easier to follow? Or even better a simple client that is heavily commented.

I wish I had more time to dive into all this... I have not even setup an LN Wallet yet because I am very anti exchange, and want mastery over the wallet, node and everything else.

Happy programming!
