+Limit API methods
+#################
+
+Sometimes you won't need all the CRUD methods.
+For example, you want to create only GET, POST and GET LIST methods,
+so user can't update or delete any items.
+
+
+Set ``methods`` on Routers registration:
+
+.. code-block:: python
+
+    RoutersJSONAPI(
+        router=router,
+        path="/users",
+        tags=["User"],
+        class_detail=UserDetailView,
+        class_list=UserListView,
+        schema=UserSchema,
+        model=User,
+        resource_type="user",
+        methods=[
+            RoutersJSONAPI.Methods.GET_LIST,
+            RoutersJSONAPI.Methods.POST,
+            RoutersJSONAPI.Methods.GET,
+        ],
+    )
+
+
+This will limit generated views to:
+
+========================  ======  =============  ===========================
+URL                       method  endpoint       Usage
