 Decort SDK - это библиотека, написанная на языке GO, позволяющая взаимодействовать с API облачной платформы **DECORT**. Библиотека содеражит в себе структуры и методы, необходимые для отправки запросов. Decort SDK имеет встроенный http-клиент и поддерживает разные способы авторизации на платформе. Библиотека так же содержит в себе модели ответов от платформы.

+## Версии

 Создание клиента происходит с помощью функции-строителя `New` из основного пакета `decort-sdk`, для избежания проблем с именами, пакету можно присвоить алиас `decort`. Функция принимает конфигурацию, возвращает структуру `DecortClient`, с помощью которой можно взаимодействовать с платформой.

+### 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"

+## Работа с legacy клиентом
+
+Работа с legacy клиентом применяется для пользователей, которые не используют для авторизации decs3o.
+
+### Настройка конфигурации legacy клиента
+
+Сначала, необходимо создать переменную конфигурации клиента. Конфигурация состоит как из обязательных, так и необязательных полей.
+
+| Поле          | Тип    | Обязательный | Описание                                                           |
+| ------------- | ------ | ------------ | ------------------------------------------------------------------ |
+| Username      | string | Да           | username legacy пользователя                                       |
+| Password      | string | Да           | пароль legacy пользователя                                         |
+| DecortURL     | string | Да           | URL адрес платформы, с которой будет осуществляться взаимодействие |
+| Retries       | uint   | Нет          | Кол-во неудачных попыток выполнения запроса, по умолчанию - 5      |
+| Timeout       | config.Duration | Нет | Таймаут HTTP клиента, по умолчанию - без ограничений               |
+| SSLSkipVerify | bool   | Нет          | Пропуск проверки подлинности сертификата     |
+| Token         | string | Нет          | JWT токен                                                          |
+
+#### Пример конфигурации legacy клиента
+
+```go
+import (
+    "repository.basistech.ru/BASIS/decort-golang-sdk/config"
+)
+
+func main(){
+    // Настройка конфигурации
+    legacyCfg := config.LegacyConfig{
+        Username:  "<USERNAME>",
+        Password:  "<PASSWORD>",
+        DecortURL: "https://mr4.digitalenergy.online",
+        Retries:   5,
+    }
+
+    legacyCfg.SetTimeout(5 * time.Minute)
+}
+```
+
+#### Парсинг legacy конфигурации из файла
+
+Также возможно создать переменную конфигурации из JSON или YAML файла, используя функцию `ParseLegacyConfigJSON` (или `ParseLegacyConfigYAML`) из пакета config.
+<br>
+*См. пример файлов конфигурации ниже и в директории `samples/`.*
+
+```go
+import (
+	"repository.basistech.ru/BASIS/decort-golang-sdk/config"
+)
+
+func main() {
+	// Парсинг конфигурации из YAML-файла
+	legacyCfg := config.ParseLegacyConfigYAML("<PATH>")
+}
+```
+
+#### Пример legacy JSON конфигурации
+
+```json
+{
+    "username": "<USERNAME>",
+    "password": "<PASSWORD>",
+    "decortUrl": "https://mr4.digitalenergy.online",
+    "retries": 5,
+    "timeout": "5m",
+    "sslSkipVerify": true
+}
+```
+
+#### Пример legacy YAML конфигурации
+```yaml
+username: <USERNAME>
+password: <PASSWORD>
+decortUrl: https://mr4.digitalenergy.online
+retries: 5
+timeout: 5m
+sslSkipVerify: true
+```
+### Создание legacy клиента
+
+Создание клиента происходит с помощью функции-строителя `NewLegacy` из основного пакета `decort-sdk`, для избежания проблем с именами, пакету можно присвоить алиас `decort`. Функция принимает конфигурацию, возвращает структуру `DecortClient`, с помощью которой можно взаимодействовать с платформой.
+
+#### Пример создания legacy клиента
+
+```go
+package main
+
+import (
+    "repository.basistech.ru/BASIS/decort-golang-sdk/config"
+    decort "repository.basistech.ru/BASIS/decort-golang-sdk"
+)
+
+func main() {
+    // Настройка конфигурации
+    legacyCfg := config.LegacyConfig{
+        Username:  "<USERNAME>",
+        Password:  "<PASSWORD>",
+        DecortURL: "https://mr4.digitalenergy.online",
+        Retries:   5,
+    }
+
+    legacyCfg.SetTimeout(5 * time.Minute)
+
+    // Создание клиента
+    legacyClient := decort.NewLegacy(cfg)
+}
+```
+
+#### Пример выполнения запроса
+
+```go
+package main
+
+import (
+	"fmt"
+
+    "repository.basistech.ru/BASIS/decort-golang-sdk/config"
+    decort "repository.basistech.ru/BASIS/decort-golang-sdk"
+)

+    // Настройка конфигурации
+    legacyCfg := config.LegacyConfig{
+        Username:  "<USERNAME>",
+        Password:  "<PASSWORD>",
+        DecortURL: "https://mr4.digitalenergy.online",
+        Retries:   5,
+    }
+
+    // Создание клиента
+    legacyClient := decort.NewLegacy(cfg)
+    
+    // Создание структуры запроса
+    // CreateRequest - реквест на создание виртуальной машины
+    req := kvmx86.CreateRequest{
+        RGID:    123,
+        Name:    "compute",
+        CPU:     4,
+        RAM:     4096,
+        ImageID: 321,
+    }
+
+    // Выполнение запроса
+    res, err := client.CloudAPI().KVMX86().Create(context.Background(), req)
+    if err != nil {
+        log.Fatal(err)
+    }
+
+    fmt.Println(res)
