 Building & Installing

-With meson:

+    I
+HACKING
+-------
 
-With Autotools:
+While hacking on the code generator or the `.metadata` files, you will
+need to force code regeneration with `ninja update-code`, a full rebuild
+is triggered right after.
 
-    ./autogen.sh --prefix=/usr && make install
+Updating to new GStreamer version
+--------------------------------
+
+* Make sure [bindinator] is installed on the system
+
+Make sure you are in an environement where latest `.gir` files are available (either install
+or through the `$GI_TYPELIB_PATH` env var).
+
+    ninja -C update-all
+
+* Verify newly generated code and `git add` files in `sources/generated/` and `ges/generated`
+* Commit
