+### MOTD
+
+If you want SquirrelBot to respond to "/start" messages (which is a commonly
+used phrase for starting conversations with Telegram bots), you should set the
+motd (message of the day) flag:
+
+```sh
+squirrelbot --address=http://myserver.example.com --port=80 \
+  --token=<your Telegram token> --motd="Hello! Try sending me a link."
+```
+
+### Configuration with a YAML file
+
+All command line options can also be set in a YAML config file (command line
+options override config file options). By default, SquirrelBot looks for the
+config file at `/etc/squirrelbot/config.yaml`
+
+Here is an example config file:
+
+```yaml
+address: https://myserver.example.com
+port: 80
+token: <your Telegram token>
+directory: Youtube Videos
+motd: Hello! Try sending me a link.

+### Transfering Video Files
 
 SquirrelBot downloads videos to a local directory that can be specified with the
 `--dir` option. The videos are formatted to be easy to view in Kodi. If you run
 this bot on a different server than your Kodi/media server, you will want to
 transfer your video files to your Kodi or media server box. Here are a couple
 ways to do that.
