+# Using STACKIT CDN with your own domain
+
+## Overview
+
+This guide outlines the process of creating a STACKIT CDN distribution and configuring it to make use of an existing domain using STACKIT DNS.
+
+## Steps
+
+1. **Create a STACKIT CDN and DNS Zone**
+    
+    Create the CDN distribution and the DNS zone.
+    
+    ```terraform
+    resource "stackit_cdn_distribution" "example_distribution" {
+      project_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+      config = {
+        backend = {
+          type       = "http"
+          origin_url = "mybackend.onstackit.cloud"
+        }
+        regions = ["EU", "US", "ASIA", "AF", "SA"]
+      }
+    }
+    
+    resource "stackit_dns_zone" "example_zone" {
+      project_id    = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+      name          = "My DNS zone"
+      dns_name      = "myapp.runs.onstackit.cloud"
+      contact_email = "aa@bb.ccc"
+      type          = "primary"
+    }
+    ```
+    
+2. **Add CNAME record to your DNS zone**
+
+    If you want to redirect your entire domain to the CDN, you can instead use an A record.
+    ```terraform
+    resource "stackit_dns_record_set" "example" {
+      project_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+      zone_id    = stackit_dns_zone.example_zone.zone_id
+      name       = "cdn"
+      type       = "CNAME"
+      records    = ["${stackit_cdn_distribution.domains[0].name}."]
+    }
+    ```
+    
+3. **Create a STACKIT CDN Custom Domain**
+    ```terraform
+    # Create a CDN custom domain
+    resource "stackit_cdn_custom_domain" "example" {
+      project_id      = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+      distribution_id = stackit_cdn_distribution.example_distribution.distribution_id
+      name            = "${stackit_dns_record_set.example.name}.${stackit_dns_zone.dns_name}"
+    }
+    ```
+    
+    Now, you can access your content on the url `cdn.myapp.runs.onstackit.cloud`.

+# Using STACKIT CDN with your own domain
+
+## Overview
+
+This guide outlines the process of creating a STACKIT CDN distribution and configuring it to make use of an existing domain using STACKIT DNS.
+
+## Steps
+
+1. **Create a STACKIT CDN and DNS Zone**
+    
+    Create the CDN distribution and the DNS zone.
+    
+    ```terraform
+    resource "stackit_cdn_distribution" "example_distribution" {
+      project_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+      config = {
+        backend = {
+          type       = "http"
+          origin_url = "mybackend.onstackit.cloud"
+        }
+        regions = ["EU", "US", "ASIA", "AF", "SA"]
+      }
+    }
+    
+    resource "stackit_dns_zone" "example_zone" {
+      project_id    = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+      name          = "My DNS zone"
+      dns_name      = "myapp.runs.onstackit.cloud"
+      contact_email = "aa@bb.ccc"
+      type          = "primary"
+    }
+    ```
+    
+2. **Add CNAME record to your DNS zone**
+
+    If you want to redirect your entire domain to the CDN, you can instead use an A record.
+    ```terraform
+    resource "stackit_dns_record_set" "example" {
+      project_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+      zone_id    = stackit_dns_zone.example_zone.zone_id
+      name       = "cdn"
+      type       = "CNAME"
+      records    = ["${stackit_cdn_distribution.domains[0].name}."]
+    }
+    ```
+    
+3. **Create a STACKIT CDN Custom Domain**
+    ```terraform
+    # Create a CDN custom domain
+    resource "stackit_cdn_custom_domain" "example" {
+      project_id      = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+      distribution_id = stackit_cdn_distribution.example_distribution.distribution_id
+      name            = "${stackit_dns_record_set.example.name}.${stackit_dns_zone.dns_name}"
+    }
+    ```
+    
+    Now, you can access your content on the url `cdn.myapp.runs.onstackit.cloud`.
