+::: details URL
+- Expand a URL
+- Shorten a URL
+- Get stats about one short URL
+:::
+
+## Example Usage
+
+This workflow allows you to create a short URL and get the statistics of the URL. You can also find the [workflow](https://n8n.io/workflows/815) on n8n.io. This example usage workflow uses the following nodes.
+- [Start](../../core-nodes/Start/README.md)
+- [Yourls]()
+
+The final workflow should look like the following image.
+
+![A workflow with the Yourls node](./workflow.png)
+
+### 1. Start node
+
+The start node exists by default when you create a new workflow.
+
+### 2. Yourls node (shorten: url)
+
+This node will create  a short URL for the link we specify.
+
+1. First of all, you'll have to enter credentials for the Yourls node. You can find out how to do that [here](../../../credentials/Yourls/README.md).
+2. Enter the URL that you want to shorten in the ***URL*** field.
+3. Click on ***Add Field*** and select 'Title'.
+4. Enter a title in the ***Title*** field.
+5. Click on ***Execute Node*** to run the node.
+
+In the screenshot below, you will notice that the node creates a short URL for the URL you specified.

+
+### 3. Yourls1 node (stats: url)
+
+This node will give us the statistics of the short URL that we specify. We will get the statistics for the URL that we created in the previous step.
+::: v-pre
+1. Select the credentials that you entered in the previous node.
+2. Select 'Stats' from the ***Operation*** dropdown list.
+3. Click on the gears icon next to the ***Short URL*** field and click on ***Add Expression***.
+4. Select the following in the ***Variable Selector*** section: Nodes > Yourls > Output Data > JSON > shorturl. You can also add the following expression: `{{$node["Yourls"].json["shorturl"]}}`.
+5. Click on ***Execute Node*** to run the node.
+:::

+# Kafka Trigger
+
+[Kafka](https://kafka.apache.org/) is an open-source distributed event streaming platform that one can use for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications.
+
+::: tip 🔑 Credentials
+You can find authentication information for this node [here](../../../credentials/Kafka/README.md).
+:::
+
+
+## Example Usage
+
+This workflow allows you to receive messages from a topic and send an SMS if the value of the temperature is greater than 50. You can also find the [workflow](https://n8n.io/workflows/814) on n8n.io. This example usage workflow would use the following nodes.
+- [Kafka Trigger]()
+- [IF](../../core-nodes/If/README.md)
+- [Vonage](../../nodes/Vonage/README.md)
+- [No Operation, do nothing](../../core-nodes/NoOperationDoNothing/README.md)
+
+The final workflow should look like the following image.
+
+![A workflow with the Kafka Trigger node](./workflow.png)
+
+
+### 1. Kafka Trigger node
+
+This node will trigger the workflow when a new message is sent to the topic `test_topic`. If you're using a different topic, use that instead. We are sending the message `{ "id": 1, "temp": 100 }` to `test_topic`.
+
+1. First of all, you'll have to enter credentials for the Kafka Trigger node. You can find out how to do that [here](../../../credentials/Kafka/README.md).
+2. Enter the name of the topic in the ***Topic*** field.
+3. Enter the group ID in the ***Group ID*** field.
+4. Click on ***Add Option*** and select 'JSON Parse Message'.
+5. Toggle ***JSON Parse Message*** to `true`.
+6. Click on ***Execute Node*** to run the node.
+
+In the screenshot below, you will notice that the node gets triggered when a new message is sent to the `topic_test` topic in Kafka.
+
+![Using the Kafka Trigger node to get a message from a topic](./KafkaTrigger_node.png)
+
+### 2. IF node
+
+This node will compare the value of `temp` that we received in the message from the previous node. If the value is greater than 50, it will return true otherwise false.
+::: v-pre
+1. Click on ***Add Condition*** and select 'Number' from the dropdown list.
+2. Click on the gears icon next to the ***Value 1*** field and click on ***Add Expression***.
+3. Select the following in the ***Variable Selector*** section: Nodes > Kafka Trigger > Output Data > JSON > message > temp. You can also add the following expression: `{{$node["Kafka Trigger"].json["message"]["temp"]}}`.
+4. Select 'Larger' from the ***Operation*** dropdown list.
+5. Set ***Value 2*** to 50.
+6. Click on ***Execute Node*** to run the node.
+:::
+
+In the screenshot below, you will notice that the node returns output for **true** when the temperature is greater than 50.
+
+![Using the IF node to check if the temp is larger than 50](./IF_node.png)
+
+### 3. Vonage node (send: sms)
+
+This node sends an SMS to the specified phone number when the value of `temp` is greater than `50`.
+
+1. Create a Vonage node connected to the 'true' output of the IF node.
+2. You'll have to enter credentials for the Vonage node. You can find out how to do that [here](../../../credentials/Vonage/README.md).
+3. Enter the name of the sender in the ***From*** field. If you're using a number, enter the number instead.
+4. Enter the receiver's phone number in the ***To*** field.
+5. Click on the gears icon next to the ***Message*** field and click on ***Add Expression***.
+::: v-pre
+6. Enter the following in the ***Expression*** field.
+```
+Alert!
+The value of temp is {{$node["Kafka Trigger"].json["message"]["temp"]}}.
+```
+7. Click on ***Execute Node*** to run the node.
+:::
+
+In the screenshot below, you will notice that the node sends an SMS with the value of `temp` that we received from the Kafka Trigger node.
+
+![Using the Vonage node to send an SMS](./Vonage_node.png)
+
+### 4. NoOp node
+Adding this node here is optional, as the absence of this node won't make a difference to the functioning of the workflow.
+
+1. Create a ***NoOp*** node connected to the 'false' output of the IF node.
+2. Click on ***Execute Node*** to run the node.
