+    <p>The config window will allow you to set the powerlevel (-30 to 100 db) and the TLM count and period values.</p>
+    <p>TLM stands for telemetry data and is a type of packet sent alongside the main packet that provides diagnostics information.
+    The count and period determine the ratio of TLM packets sent versus normal packets.
+    A period of 10 and a count of 2 means that 2 TLM packets are sent for each 10 advertisements.</p>
+
+    <p>The actual advertisement rate can be set by changing the <code>BLENO_ADVERTISING_INTERVAL</code> environment variable.
+    For example, to set a 20ms interval, you would need to type <code>sudo BLENO_ADVERTISING_INTERVAL=20 node-red</code></p>
