+### Фильтрация
+
+Для каждого `ListRequest` в SDK есть группа функций для фильтрации ответа платформы. Для того чтобы произвести фильтрацию по заданным полям, достаточно описать анонимную функцию (предикат) в `.FilterFunc()`, например:
+
+```go
+// Создание запроса account/list
+req := account.ListRequest{}
+
+resp, err := client.CloudAPI().Account().List(context.Background(), req)
+if err != nil {
+	log.Fatal(err)
+}
+
+// Тип filtered - ListAccount, тот же, что и у ответа платформы.
+filtered := resp.
+	FilterFunc(func(ia account.ItemAccount) bool {
+	// ItemAccount открывает доступ к полям модели ответа платформы.
+		for _, itemAcl := range ia.ACL {
+			if itemAcl.UgroupID == "<UserGroupID>" { // Фильтр по ACL/UgroupID
+				return true
+			}
+		}
+		return false
+	})
+```
+
+Для удобства пользователей, особенно важные фильтры вынесены в отдельные функции, что облегчает фильтрацию сразу по нескольким полям:
+
+```go
+// Создание запроса account/list
+req := account.ListRequest{}
+
+resp, err := client.CloudAPI().Account().List(context.Background(), req)
+if err != nil {
+	log.Fatal(err)
+}
+
+// Несколько фильтров объединены в конвейер
+filtered := resp.
+	FilterByName("<NAME>").
+	FilterByStatus("<STATUS>")
+	// ....
+```
+
+Также у `compute`, `disks`, и `lb` присутствуют специфические функции фильтрации, отправляющие дополнительные запросы. В качестве параметров принимают:
+- context.Context - контекст для доп. запроса
+- id (или другое поле, по которому производится фильтрация)
+- interfaces.Caller - DECORT-клиент для запроса
+
+Так как эти функции возвращают не только результирующий слайс, но и возможную ошибку - конвейер придется прервать для обработки ошибки.
+
+
+#### Использование на примере `compute.FilterByK8SID`:
+
+```go
+func main() {
+    // Чтение конфигурации из файла
+    cfg := config.ParseConfigJSON("<PATH>")
+
+    // Создание клиента
+    client := decort.New(cfg)
+
+    // Создание структуры запроса compute/list
+    req := compute.ListRequest{}
+
+    // Запрос
+    resp, err := client.CloudAPI().Compute().List(context.Background(), req)
+    if err != nil {
+        log.Fatal(err)
+    }
+
+    // Фильтрация по id кластера.
+    // Первый аргумент - контекст
+    // Второй - ID кластера
+    // Третий - DECORT-клиент
+    filtered, err := resp.FilterByK8SID(context.Background(), <k8sID>, client)
+    if err != nil {
+        log.Fatal(err) // Возможная ошибка запроса
+    }
+
+    // Доп. фильтрация и сортировка результата - worker ноды кластера
+    workers := filtered.FilterByK8SWorkers().SortByCreatedTime(false)
+
+    // Доп. фильтрация и сортировка результата - master ноды кластера
+    masters := filtered.FilterByK8SMasters().SortByCreatedTime(true)
+
+    // ....
+}
+```
+
+### Сортировка
+
+Функции сортировки так же могут быть объединены в конвейер:
+
+```go
+// Создание запроса compute/list
+req := compute.ListRequest{}
+
+resp, err := client.CloudAPI().Compute().List(context.Background(), req)
+if err != nil {
+	log.Fatal(err)
+}
+
+// Функции сортировки имеют параметр inverse (bool):
+// При значении false -> сортировка по возрастанию
+// При true -> сортировка по убыванию
+sorted := resp.
+	SortByCPU(false).
+	SortByRAM(false).
+	SortByCreatedTime(true)
+	// ....
+```
+
+### Сериализация
+
+Результат преобразований легко сериализовать в JSON при помощи функции `.Serialize()`. Она принимает в себя 2 необязательных аргумента: префикс (prefix) и отступ (Indent).
+
+В случае если функция вызывается без аргументов, то маршализация пройдет успешно, но без отступов и префиксов.
+
+```go
+// Сериализация данных с префиксом "" и отступом "\t"
+serialized, err := filtered.Serialize("", "\t")
+if err != nil {
+	log.Fatal(err)
+}
+
+// Запись сериализованных данных в файл
+err = serialized.WriteToFile("<PATH>")
+if err != nil {
+	log.Fatal(err)
+}
+```
+
+#### Комплексный пример
+
+```go
+package main
+
+import (
+	"context"
+	"log"
+
+	decort "repository.basistech.ru/BASIS/decort-golang-sdk"

+		DecortURL:     "<DECORT_URL>",
+		Retries:       5,
+	}
+	
+	// Создание клиента
+	client := decort.New(cfg)
+
+	// Создание запроса compute/list
+	req := compute.ListRequest{}
+
+	resp, err := client.CloudBroker().Compute().List(context.Background(), req)
+	if err != nil {
+		log.Fatal(err)
+	}
+
+	// Цепь преобразований.
+	filtered, _ := resp.
+        FilterFunc(func(ic compute.ItemCompute) bool {
+            return ic.GUID == 123 // Фильтр по GUID
+        }).
+        FilterByName("<NAME>"). // Фильтр по имени
+        SortByCPU(false). // Сортировка по кол-ву ядер CPU по возрастанию
+        SortByCreatedTime(true). // Сортировка по времени создания по убыванию
+        Serialize("", "\t") // Сериализация с префиксом "" и отступом "\t"
