+# Skeleton plugin
+
+This is a skeleton plugin i.e. the minimal plugin boilerplate.
+
+It adds an owner and message mapping key and print it when reading or writing
+the parameter.
+
+## Usage
+
+It has no purpose: it only serves as a template and the `make install` target
+does not install it.  If you want to see a real-life plugin and makefiles, see
+<https://github.com/01org/parameter-framework-plugins-alsa> instead.
