+meson - Meson build element
+===========================
+This is a `BuildElement
+<https://docs.buildstream.build/master/buildstream.buildelement.html#module-buildstream.buildelement>`_
+implementation for using `Meson <http://mesonbuild.com/>`_ build scripts.
+
+You will often want to pass additional arguments to ``meson``. This should
+be done on a per-element basis by setting the ``meson-local`` variable.  Here is
+an example:
+
+.. code:: yaml
+
+   variables:
+     meson-local: |
+       -Dmonkeys=yes
+
+If you want to pass extra options to ``meson`` for every element in your
+project, set the ``meson-global`` variable in your project.conf file. Here is
+an example of that:
+
+.. code:: yaml
+
+   elements:
+     meson:
+       variables:
+         meson-global: |
+           -Dmonkeys=always
+
+Here is the default configuration for the ``meson`` element in full:
+
+  .. literalinclude:: ../../../src/buildstream_plugins/elements/meson.yaml
+     :language: yaml
+
+See `built-in functionality documentation
+<https://docs.buildstream.build/master/buildstream.buildelement.html#core-buildelement-builtins>`_ for
+details on common configuration options for build elements.
