+## Add a bundle product with selected options to a cart
+
+The following example adds the Sprite Yoga Companion Kit bundle product to the cart. The bundle product is comprised of four simple products, and the selected simple products are specified with a value in the `selected_options` array. Use the `products` query to determine these UID values. Note that each UID value is an encoded value representing the following string:
+
+`bundle/<bundle_option_id>/<bundle_option_selection_id>/<quantity>`
+
+Because the encoded value includes the quantity, the schema does not contain a `quantity` attribute for individual simple products.
+
+In this example, the UID values are encoded versions of these strings:
+
+```text
+bundle/1/1/1
+bundle/2/4/1
+bundle/3/5/1
+bundle/4/8/1
+```

+### Add a bundle product with entered options to the cart
+
+For `entered_options`, the `uid` attribute contains the encoded entered value. The `value` attribute defines the quantity. If the `BundleProduct.items.options.can_change_quantity` attribute is `false`, then the bundle product definition sets the quantity for the simple product. Otherwise, the shopper decides the quantity.
+
+The Luma sample data does not provide any bundle products with entered options. The following snippet shows how to construct the mutation.
+
+```graphql
+mutation {
+  addProductsToCart(
+    cartId: "ELwvX8VJinGJ9Q2vOXSiCTS4gvCDKP8U"
+    cartItems: [
+      {
+        quantity: 1
+        sku: "bundle1"
+        entered_options: [
+          {
+            uid: "EncodedEnteredValue1"
+            value: 1
+          }
+        ]
+        selected_options: [
+          "EncodedSelectedValue1"
+          "EncodedSelectedValue2"
+        ]
+      }
+    ]
+  ) {
