+## Matrix Fields
+Working with Matrix Fields are similar to working with Entry Types: if you have a Matrix Field named `pagebuilder`, the containing Block Types are named `PageBuilder` + the block name. For instance `PageBuilderText` or `PageBuilderImage`. You can use the key `__typename` from the resulting response to map over the blocks and display the appropriate component.
+
+```graphql
+{
+  entries(section: [news]) {
+    ... on News {
+      id
+      title
+      body {                  # Your Matrix Field
+        ... on BodyText {     # Block Type
+          blockHeading        # Fields on Block Type, uses field handle
+          blockContent        # Fields on Block Type, uses field handle
+        }
+        ... on BodyImage {    # Block Type
+          blockDescription    # Fields on Block Type, uses field handle
+          image {             # Fields on Block Type, uses field handle
+            id                # Fields on image field on Block Type, uses field handles
+          }
+        }
+      }
+    }
+  }
+}
+```
