+  <para>
+    Unregisters a standby with `repmgr`. This command does not affect the actual
+    replication, just removes the standby's entry from the &repmgr; metadata.
+  </para>
+  <para>
+    To unregister a running standby, execute:
+    <programlisting>
+      repmgr standby unregister -f /etc/repmgr.conf</programlisting>
+  </para>
+  <para>
+    This will remove the standby record from &repmgr;'s internal metadata
+    table (<literal>repmgr.nodes</literal>). A <literal>standby_unregister</literal>
+    event notification will be recorded in the <literal>repmgr.events</literal> table.
+  </para>
+  <para>
+   If the standby is not running, the command can be executed on another
+   node by providing the id of the node to be unregistered using
+   the command line parameter <literal>--node-id</literal>, e.g. executing the following
+   command on the master server will unregister the standby with
+   id <literal>3</literal>:
+   <programlisting>
+    repmgr standby unregister -f /etc/repmgr.conf --node-id=3
+   </programlisting>
