+### Create a Notification Template
+
+For each notification type you want to send, you need to create a template in Novu. This is a one-time setup step that you can do on the Novu web interface. 
+
+It is possible to customize the notification content at each invocation via handlebars-style placeholders. For example, you can create a template for an email notification that looks like this:
+
+```
+Hello {{name}},
+{{content}}
+```
+
+The placeholders will be replaced with the actual values of the `payload` object you pass to the `send` method.
+
+To create a template, follow these steps:
+
+1. Open https://web.novu.co and sign in with your Novu account credentials
+
+2. Click "Notifications"

+
+4. Double-click the "notification name" field and enter the name of the template. This is the event name with which the respective notification may be triggered from the API.
