I followed those as well but changed to whats in the gtk-rs book
A word of warning: before you start, if you choose to go down the MSVC path, you have to uinstall msys2 and remove msys from your environment paths. If the Meson build find msys2 in your environment path variable, it will try to build using msys2.
gtk-rs has a book[1] which has setup information for windows. The install was easy on windows following the instructions. I have yet to build an app with GTK4 so I can't comment on the writing and building of apps just yet.
What would I bingle for if I was looking for a template for such an agreement/contract? It seems like the kind of thing you would want to have prepared in advance (in case of emergency, break glass).
