-The GTK sources are hosted on [gitlab.gnome.org](http://gitlab.gnome.org). The main
-development branch is called `main`, and stable branches are named after their minor
-version, for example `gtk-4-10`.
+The default development branch of GTK has been renamed to `main`.
+To update your local checkout, use:
+```sh

+git branch -m master main
+git fetch
+git branch --unset-upstream
