 CertStream is a service that provides real-time certificate transparency log updates. This integration allows ingesting CertStream data into our platform to detect new domain certificates in real-time.
 
+## Prerequisites
+
+Before using the `Certstream` integration, ensure that you have completed the following steps:
+
+1. **Create Domain's Homographs List**: Run the `Create list for PTH` playbook in the playground to generate a list of domains and their homographs or create the list manually with the expected format: 
+
+```json
+{
+  "domain1": [
+    "domain1_homograph1",
+    "domain1_homograph2",
+    "domain1_homograph2"
+  ],
+  "domain2": [
+    "domain2_homograph1",
+    "domain2_homograph2",
+    "domain2_homograph3"
+  ]
+}
+```
+
+After the list is created in the valid format, proceed with configuring integration instance.
+
 ## Usage
 
 The integration connects to the CertStream public API server and watch the certificate transparency log.
