-#### Performance Testing
+#### Subclassing paginators
+
+The JSON API pagination classes can be subclassed to override settings as
+described in the [DRF pagination documentation](http://www.django-rest-framework.org/api-guide/pagination/).
+
+The default values are shown in these examples:
+
+```python
+from rest_framework_json_api.pagination import PageNumberPagination, LimitOffsetPagination
+
+class MyPagePagination(PageNumberPagination):
+    page_query_param = 'page'
+    page_size_query_param = 'page_size'
+    max_page_size = 100
+
+class MyLimitPagination(LimitOffsetPagination):
+    offset_query_param = 'page[offset]'
+    limit_query_param = 'page[limit]'
+    max_limit = None
+```
+
+As shown above, pages can be selected with the `page` or `page[limit]` GET query parameter when using
+the PageNumberPagination or LimitOffsetPagination class, respectively. 
+
+If you want to use the PageNumberPagination query parameter names shown
+as an example in the JSON API [specification](http://jsonapi.org/format/#fetching-pagination),
+set them as follows:
+```python
+class MyPagePagination(PageNumberPagination):
+    page_query_param = 'page[number]'
+    page_size_query_param = 'page[size]'
+```
+
+#### Setting global defaults for pagination
+
+Set global defaults for the `PageNumberPagination` class with these settings:
+- `JSON_API_PAGE_NUMBER_PARAM` sets the name of the page number query parameter (default: "page").
+- `JSON_API_PAGE_SIZE_PARAM` sets the name of the page size query parameter (default: "page_size").
+- `JSON_API_MAX_PAGE_SIZE` sets an upper limit for the page size query parameter (default: 100).
+
+Set global defaults for the `LimitOffsetPagination` class with these settings:
+- `JSON_API_PAGE_OFFSET_PARAM` sets the name of the page offset query parameter (default: "page\[offset\]").
+- `JSON_API_PAGE_LIMIT_PARAM` sets the name of the page limit query parameter (default: "page\[limit\]").
+- `JSON_API_MAX_PAGE_LIMIT` sets an upper limit for the page limit query parameter (default: None).
+
+If you want to set the default PageNumberPagination query parameter names shown
+as an example in the JSON API [specification](http://jsonapi.org/format/#fetching-pagination),
+set them as follows:
+```python
+JSON_API_PAGE_NUMBER_PARAM = 'page[number]'
+JSON_API_PAGE_SIZE_PARAM = 'page[size]'
+```

-#### Performance Testing
+#### Configuring the Pagination Style
+
+Pagination style can be set on a particular viewset with the `pagination_class` attribute or by default for all viewsets
+by setting `REST_FRAMEWORK['DEFAULT_PAGINATION_CLASS']` and by setting `REST_FRAMEWORK['PAGE_SIZE']`.
+
+You can configure fixed values for the page size or limit -- or allow the client to choose the size or limit
+via query parameters.
+
+Two pagination styles are available:
+- **PageNumber** breaks a response up into pages that start at a given page number with a given size 
+  (number of items per page). Two classes are available: `JsonApiPageNumberPagination` 
+  and `PageNumberPagination` (deprecated). They can be configured with the following attributes:
+  - `page_query_param` (default `page[number]` for `JsonApiPageNumberPagination`; `page` for `PageNumberPagination`.)
+  - `page_size_query_param` (default `page[size]` for `JsonApiPageNumberPagination`; `page_size` 
+     for `PageNumberPagination`.) Set this to `None` if you don't want to allow the client to specify the size.
+  - `max_page_size` (default `100`) enforces an upper bound on the `page_size_query_param`.
+     Set it to `None` if you don't want to enforce an upper bound.
+- **LimitOffset** breaks a response up into pages that start from an item's offset in the viewset for a given number of
+  items (the limit). Two classes are available: `JsonApiLimitOffsetPagination` and `LimitOffsetPagination` (deprecated).
+  They can be configured with the following attributes:
+  - `offset_query_param` (default `page[offset]`).
+  - `limit_query_param` (default `page[limit]`).
+  - `max_limit` (default `100` for JsonApiLimitOffsetPagination; `None` for `LimitOffsetPagination`) enforces an upper
+     bound on the limit. Set it to `None` if you don't want to enforce an upper bound.
+
+
+These examples show how to configure the parameters to use non-standard names and different limits:
+
+```python
+from rest_framework_json_api.pagination import JsonApiPageNumberPagination, JsonApiLimitOffsetPagination
+
+class MyPagePagination(JsonApiPageNumberPagination):
+    page_query_param = 'page_number'
+    page_size_query_param = 'page_size'
+    max_page_size = 1000
+
+class MyLimitPagination(JsonApiLimitOffsetPagination):
+    offset_query_param = 'offset'
+    limit_query_param = 'limit'
+    max_limit = None
+```
+
+#### Deprecated Pagination Classes
+
+The `JsonApiPageNumberPagination` and `JsonApiLimitOffsetPagination` classes implement the *recommended*
+query parameter names found in the [JSON:API specification](http://jsonapi.org/format/#fetching-pagination).
+
+`PageNumberPagination` and `LimitOffsetPagination` are deprecated and may be removed in a future release as they
+use different defaults for query parameters: `page` and `page_size` query parameters are the defaults for 
+`PageNumberPagination`. Also, `JsonApiLimitOffsetPagination` sets a default `max_limit = 100` whereas the 
+`LimitOffsetPagination` class sets no max limit. To avoid a breaking change, these classes and default values
+have been retained for the time being.

-`PageNumberPagination` and `LimitOffsetPagination` are deprecated and may be removed in a future release as they
-use different defaults for query parameters: `page` and `page_size` query parameters are the defaults for 
-`PageNumberPagination`. Also, `JsonApiLimitOffsetPagination` sets a default `max_limit = 100` whereas the 
-`LimitOffsetPagination` class sets no max limit. To avoid a breaking change, these classes and default values
-have been retained for the time being.
