 This project requires a config file that should look like this:
 
 ```yml
+discord:
+  avatar_url: <PUBLIC URL OF AN IMAGE>
+  username: <AWESOME USER NAME>
+  webhook_url: <DISCORD WEBHOOK URL>
 slack:
   channel: <AWESOME CHANNEL NAME>
   username: <AWESOME USER NAME>
   webhook_url: <SLACK WEBHOOK URL>
   icon_emoji: ':<SOME EMOJI>:'

 ```bash
 slack-messaging setup
 ```
 
-To obtain the webhook URL, go to [this link](https://api.slack.com/messaging/webhooks).

 If you'd like to create the config file at a different directory, I recommend using the `setup` command, and then manually moving the file to your desired location:
 
 ```bash
 slack-messaging setup
 # Walk through the prompts to create the file
 mv ~/.slack_messaging.yml /PATH/TO/FILE/config.yml
 ```

+If your config file contains both Slack and Discord settings, then running a basic `send` command (either passing in a message or not), will notify both Slack and Discord. To specify which service to send a message to, you can pass in a `-s`/`--service` flag:
+
+```bash
+slack-messaging send --service slack
+# OR
+slack-messaging send --service discord

+To specify a service _and_ send a customized message, you can pass both at once:
