+# 1. SLAVE NETDATA - THE ONE THAT WILL BE SENDING METRICS
+#
+#    In /etc/netdata/netdata.conf you have a configuration like this:
+#
+#    [stream]
+#
+#        # enable or disable sending metrics.
+#        # default: no
+#           enabled = yes

+#        # when set to yes, the slave netdata will not start
+#        # its web server and will not maintain a database.
+#        # when set to yes, the slave netdata will be just a metrics collector.
+#        # default: yes
+#           exclusive = yes
+#
+#        # one or more netdata hosts to send metrics to.
+#        # only one will get them, the first available.

+# 2. MASTER NETDATA - THE ONE THAT WILL BE RECEIVING METRICS
+#
+#    You need an API key: API_KEY_GENERATED_BY_UUIDGEN
+#    This key should be specified at the master and the slave netdata servers.
 #
 #    You can generate one with the command: uuidgen
-#    You can add many API key sections, for different API keys
+#    You can add many API key sections below, for each API key.
+#
+#    You can have one API key per slave, or the same API key for all slaves.
+#    Each slave will automatically create its own virtual host at the master
+#    even if all slaves use the same API key.

-#    Of course, the same API_KEY_GENERATED_BY_UUIDGEN key must
