   echo Hello world c=1 d=2
   ```
   This will send "Hello world" to channel 1, device 2.
+#### MOTD Substitution
+
+- In admin echo, if you include the word `motd` or `MOTD` (case-insensitive) anywhere in your message, it will be replaced with the current Message of the Day.
+- Example:
+  ```
+  echo Today's message is motd c=1 d=2
+  ```
+  If the MOTD is "Potatos Are Cool!", the message sent will be:
+  ```
+  Today's message is Potatos Are Cool!
+  ```
+
+#### Notes
+- Only admins can use the `c=<channel>` and `d=<device>` override.
+- If you omit `c=<channel>` and `d=<device>`, the message is echoed back to your current channel/device.
+- MOTD substitution works for any standalone `motd` or `MOTD` in the message.
