+## Example Usage
+
+This workflow allows you to create an invoice with the information received via a Typeform submission. You can also find the [workflow](https://n8n.io/workflows/989) on n8n.io. This example usage workflow would use the following nodes.
+- [Typeform Trigger](../../trigger-nodes/TypeformTrigger/README.md)
+- [APITemplate.io]()
+
+The final workflow should look like the following image.
+
+![A workflow with the APITemplate.io node](./workflow.png)
+
+### 1. Typeform Trigger node
+
+This node will trigger the workflow when a form is submitted. Make sure to create a form that collects the following information:
+- Bill To (Short Text)
+- Client's Email Address (Email)
+- Item Description (Short Text)
+- Item Price (Number)
+- Item Description (Short Text)
+- Item Price (Number)
+

+
+### 2. APITemplate.io node (create: pdf)
+
+This node will generate an invoice using the information from the previous node. Create an invoice template in APITemplate.io, if you don't already have one.
+
+1. First of all, you'll have to enter credentials for the APITemplate.io node. You can find out how to do that [here](../../../credentials/APITemplateIo/README.md).
+2. Select 'PDF' from the ***Resource*** dropdown list.
+3. Select your invoice template from the ***Template ID*** dropdown list.
+4. Toggle ***JSON Parameters*** to `true`. By setting this option to true, the node allows us to write custom JSON data.
+5. Toggle ***Download*** to `true`.
+6. Click on the gears icon next to the ***Properties (JSON)*** field.
+7. Enter the following expression in the ***Edit Expression*** field:
+```json

+  "email": "{{$json["1"]["email"]}}",
+  "invoice_no": "213223444",
+  "invoice_date": "18-03-2021",
+  "invoice_due_date": "17-04-2021",
+  "address": "Berlin, Germany",
+  "company_bill_to": "{{$json["0"]["text"]}}",
+  "website": "https://n8n.io",

+9. Enter a file name in the ***File Name*** field.
+10. Click on ***Execute Node*** to run the node.
