+# nfacct.plugin
+
+This plugin that collects NFACCT statistics.
+
+It is currently disabled by default, because it requires root access.
+We have to move the code to an external plugin to setuid just the plugin not the whole netdata server.
+
+You can build netdata with it to test it though.
+Just run `./configure` (or `netdata-installer.sh`) with the option `--enable-plugin-nfacct` (and any other options you may need).
+Remember, you have to tell netdata you want it to run as `root` for this plugin to work.
