+### Building with specific plugins
+
+By default, all vendor plugins are built. To build only specific plugins, use the `plugins` option:
+
+	$ meson setup .build -Dplugins=intel,wdc,ocp
+	$ meson compile -C .build
+
+Or with the Makefile wrapper:
+
+	$ make PLUGINS="intel,wdc,ocp"
+
+When `PLUGINS` is not used, the value defaults to `all`, which selects all plugins:
+
+	$ make PLUGINS="all"
+
+To build without any vendor plugins:
+
+	$ make PLUGINS=""
+
 ## Distro Support
