+Xref plugin
+------------
+
+This plugin is available by default. It adds the following
+target:
+
+`xref` Erlang Xref Runner (inspired in rebar's rebar_xref)
+
+The `XREF_CONFIG` variable specifies the location of the
+configuration file which holds the checks to be applied.
+If there is no `xref.config` all `xref` checks will be
+applied to the binaries located in the `/ebin` directory.
