+```hcl
+resource "github_organization_custom_properties" "environment" {
+  property_name = "environment"

+  description   = "The deployment environment for this repository"
+  default_value = "development"
+  allowed_values = [
+    "development",
+    "staging", 
+    "production"
+  ]
+}
+```
+

+resource "github_organization_custom_properties" "owner" {
+  property_name = "owner"
+  value_type    = "string"
+  required      = true
+  description   = "The team or individual responsible for this repository"
+}
+```
+
+## Example Usage - Boolean Property
+
+```hcl
+resource "github_organization_custom_properties" "archived" {
+  property_name = "archived"
+  value_type    = "true_false"
+  required      = false
+  description   = "Whether this repository is archived"
+  default_value = "false"
+}
+```
