Hello!
Eddie GUI is built for Intel architecture because it is written in C#, thus runs in the Mono framework that is not available for ARM / Apple Silicon. Eddie backend is entirely written in C++ and when you download the package for ARM you get an Eddie backend built and optimized for ARM 64 bit. Eddie CLI is built for ARM 64 bit as well.
Kind regards
That forum is not for untested, WIP guides. Finish it, incorporate others' feedback, then it might get moved if verified to work.
Please also make it clear why you wish to write another guide if the existing one still works.
