-#### Event-connector pattern
+### Event-connector pattern
 
 The OpenFaaS connector-pattern allows you to create a broker or separate microservice which maps functions to topics and invokes functions via the OpenFaaS Gateway meaning that the OpenFaaS code does not need to be modified per trigger/event-source.

-##### Add your own event source
+#### Add your own event source
 
 If you'd like to add an event source which is not listed below you can fork the OpenFaaS event [connector SDK](https://github.com/openfaas-incubator/connector-sdk) which is written in Go and use this to connect your pub/sub topics or message queues to functions in OpenFaaS.
 
-#### Apache Kafka
+### Apache Kafka
 
 Connect your function(s) to [Apache Kafka](https://kafka.apache.org) topics.
 
 More information in the Incubator repository: [openfaas-incubator/kafka-connector](https://github.com/openfaas-incubator/kafka-connector)
 
 Support is available for OpenFaaS Gateways using Basic Authentication.
 
-#### AWS SNS
+### AWS SNS
 
 You can use AWS SNS to trigger functions using AWS SNS Notifications and Subscriptions. This approach can be used to export almost any data-source or event from your Amazon Web Services (AWS) console such as S3 of DynamoDB to an OpenFaaS function.
 
 Find more information in the following repository: [affix/OpenFaaS-SNS](https://github.com/affix/OpenFaaS-SNS)
 
-#### Minio / S3
+### Minio / S3
 
 You can trigger OpenFaaS functions using Minio's webhook or Kafka integration.

 * [Minio's Kafka integration](https://docs.minio.io/docs/minio-bucket-notification-guide.html#apache-kafka)
 
-#### IFTTT
+### CloudEvents
 
-You can trigger OpenFaaS functions using webhooks sent via the (if this, then that) service.
+[CloudEvents](https://cloudevents.io/) is a specification for describing event data in a common way.
 
-An example may be triggering a function which forwards Tweets about your brand or project to a given Slack channel. For this combination use the "Twitter search" Applet and have it trigger the "Make a web request" Applet giving the public URL of your OpenFaaS gateway and the receiver function such as https://gw.my-company.com/function/slack-forwarder
+Follow this example to learn how to trigger functions using the Azure EventGrid and CloudEvents.
 
-See an example of a function built to forward Tweets from IFTTTT to Slack using Golang: [filter-tweets](https://github.com/openfaas-incubator/social-functions/blob/master/filter-tweets/handler.go).
