+### Email And Slack Notifications
+
+By default, SimpleDiscussion will attempt to send email and slack notifications for users subscribed to threads. To turn these off you can do the following in `config/initializers/simple_discussion.rb`
+
+```ruby
+SimpleDiscussion.setup do |config|
+  config.send_email_notifications = false # Default: true
+  config.send_slack_notifications = false # Default: true
+end
+```
+
+Slack notifications require you to set `simple_discussion_slack_url` in your `config/secrets.yml`. If you don't have this value set, it will not attempt Slack notifications even if they are enabled.
