+## Custom Metadata
+
+By default, the following fields are present in the metadata block:
+
+```graphql
+metadata {
+  totalPages
+  totalCount
+  currentPage
+  limitValue
+}
+```
+
+These fields correspond to the `GraphqlPagination::CollectionMetadataType` used to provide the pagination information for the collection of data delivered. If you want to add more metadata fields to this block, you can do so by extending this `CollectionMetadataType`:
+
+```ruby
+class MyMetadataType < GraphqlPagination::CollectionMetadataType
+  field :custom_field, String, null: false
+end
+
+field :fruits, Types::FruitType.collection_type(metadata_type: MyMetadataType)
+```
