+
+```sh
+$ git clone git@gitlab.gnome.org:GNOME/gtk.git

 To compile the Git version of GTK on your system, you will need to
 configure your build using Meson:
 
 ```sh
-$ meson setup _builddir .
+$ meson _builddir .
-$ meson compile -C _builddir
+$ cd _builddir
+$ ninja
 ```
 
 Typically, you should work on your own branch:
 
 ```sh
-$ git switch -C your-branch

 Once you've finished working on the bug fix or feature, push the branch
 to the Git repository and open a new merge request, to let the GTK
 maintainers review your contribution.

 You can run the test suite using:
