 This is the safe wrapper for [gtk-layer-shell](https://github.com/wmww/gtk-layer-shell), automatically generated from its [.gir file](GtkLayerShell-0.1.gir). For details on how to use it or how to generate the code yourself, have a look at the crate's [README](https://github.com/pentamassiv/gtk-layer-shell-gir/tree/main/gtk-layer-shell/README.md). The unsafe bindings can be found in this [folder](https://github.com/pentamassiv/gtk-layer-shell-gir/tree/main/gtk-layer-shell-sys). These crates are GTK3 only. Use [gtk4-layer-shell-sys](https://crates.io/crates/gtk4-layer-shell-sys) or [gtk4-layer-shell](https://crates.io/crates/gtk4-layer-shell) if you need to use it with GTK4.
 
 ## Maintenance status
-These crates are just wrappers for the C library so it is feature complete and not actively worked on. There are Github Actions keeping the dependencies up-to-date. If you encounter any problems, feel free to open a PR.
+The Rust bindings for GTK3 are no longer maintained and the repo has been archived. If you are starting a new project, you should use GTK4 and thus gtk4-layer-shell right from the start.
