+    <p>In <strong>URL mode</strong> this node can take the value of <code>msg.payload</code> and publishes it as an Eddystone URL
     announcement. URLs <b>must</b> be less than 18 bytes long, so should be run through a shortner first.</p>
     <p>You can also preset the URL, in which case the node does not require any input.</p>
-    <p>The config window will allow you to set the powerlevel (-30 to 100 db) and the period (S)
-    between anouncements.</p>
+    <p>In <strong>UID mode</strong> this node can take the 10 bytes namespace (as an HEX string) as <code>msg.payload</code>
+    and the 6 bytes instance (as an HEX string) as <code>msg.topic</code>.
+    <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>
