 Once you have all the necessary dependencies, you can build GTK by using
 Meson:
 
 ```sh
-$ meson _build .
-$ cd _build
-$ ninja
+$ meson setup _build
+$ meson compile -C_build
 ```
 
 You can run the test suite using:
 
 ```sh
-$ meson test
+$ meson test -C_build
 ```
 
 And, finally, you can install GTK using:
 
 ```
-$ sudo ninja install
+$ sudo meson install -C_build
 ```
