So, the idea is to do a book for programmers (like we have thousands of books about some particular language so that programmers can learn the API). Problem is, there is no “official” API. With that in mind, for now, and until that happens, I guess we could include what we have: NDK from @fiatjaf Swift code from @jb55 @Fabian C++ code from @Pedro Vicente (actually also C code from @jb55 ) . Mix the code with the algorithms . I did not get a good idea of how to do things just by reading the NIPs. The only way I was able to know how to get a list of follows, for example, was to debug @Damus Code and dump some json to files. That is from the programming side. Also include some background for the motivation of #nostr. Like from an historical point of view, starting with the invention of the WWW by Berners-Lee. I did a small write up on that , in the link below, that tells that we need a “global digital public square that is essential to the survival of humanity” ( more or less quoting Elon Musk here) , I guess what Twitter was supposed to be (and is, but with issues it has now) https://pedro-vicente.net/
