+# Kubernetes Namespace Module
+
+**Purpose**: Create Kubernetes namespace with resource quotas and limit ranges
+**Status**: ✅ Complete
+
+---
+
+## Usage
+
+```hcl
+module "namespace" {
+  source = "../../modules/kubernetes/namespace"
+
+  name = "my-app"
+
+  labels = {
+    app     = "my-app"
+    env     = "production"
+    managed = "terraform"
+  }
+
+  annotations = {
+    description = "Namespace for my-app"
+  }
+
+  resource_quota = {
+    "requests.cpu"    = "4"
+    "requests.memory" = "8Gi"
+    "limits.cpu"      = "8"
+    "limits.memory"   = "16Gi"
+  }
+
+  limit_range = {
+    default = {
+      "cpu"    = "500m"
+      "memory" = "1Gi"
+    }
+    default_request = {
+      "cpu"    = "100m"
+      "memory" = "128Mi"
+    }
+    max = {
+      "cpu"    = "2"
+      "memory" = "4Gi"
+    }
+    min = {
+      "cpu"    = "50m"
+      "memory" = "64Mi"
+    }
+    max_limit_request_ratio = {
+      "cpu" = "4"
+    }
+  }
+}
