Doc request: methodology with github releases

[Aarbel]

@leo Thanks again hazel teams for your work !

I saw that now-desktop releases are managed like that:

My electron-builder output looks like that:

Could you tell us more about the necessity of each file in the release and put that in hazel doc ?

latest-mac.yml // Why this file ?
Now-4.0.19-mac.zip // Why a zip and not only .dmg ?
Now-4.0.19.dmg // What is downloaded on each update ? The dmg of Source code.zip ? 
Now-4.0.19.dmg.blockmap // Electron-builder doesn't generate this file for me, what's its role ? 
now-desktop-4.0.19-full.nupkg // What's this file for ? Electron-builder doesn't seem to generate it in my dist folder
now-desktop-Setup-4.0.19.exe // Ok looks like Windows installer, but same question: on each update is that all the .exe downloaded or only the Source Code.zip ?
RELEASES // That's this file is for ? 
Source code.zip // Ok the source code
Source code.tar.gz // Ok differently compressed source code

Thanks a lot for your help ! 👐
