+# Contributing
+
+## Настройки
+
+`vksdk` написан на [Go](https://golang.org/).
+
+Требования:
+
+- [Go 1.13+](https://golang.org/doc/install)
+- [golangci-lint](https://github.com/golangci/golangci-lint)
+- [global .gitignore](https://help.github.com/en/articles/ignoring-files#create-a-global-gitignore)
+
+Сделайте fork и клонируйте `vksdk` куда угодно:
+
+```sh
+git clone git@github.com:<your name>/vksdk.git
+```
+
+Создайте новую ветку
+
+```sh
+git checkout -b <name_of_your_new_branch>
+```
+
+## Тестирование изменений
+
+Для начала проверьте ваш код с помощью
+[golangci-lint](https://github.com/golangci/golangci-lint)
+
+```sh
+golangci-lint run
+```
+
+Затем можно запускать тесты
+
+```sh
+# SERVICE_TOKEN=""
+# GROUP_TOKEN=""
+# CLIENT_SECRET=""
+# USER_TOKEN=""
+# WIDGET_TOKEN=""
+# CLIENT_ID="123456"
+# GROUP_ID="123456"
+# ACCOUNT_ID="123456"
+go test ./...
+```
+
+Задавать токены не обязательно - тесты с их использованием будут пропущены.
+**Не** рекомендуется задавать свой `USER_TOKEN`, так как тесты делают много
+страшных вещей.
+
+Настройки для VSCode `.vscode/setting.json`
+
+```json
+{
+    "go.testEnvVars": {
+        "SERVICE_TOKEN": "",
+        "WIDGET_TOKEN": "",
+        "GROUP_TOKEN": "",
+        "CLIENT_SECRET": "",
+        "USER_TOKEN": "",
+        "CLIENT_ID": "123456",
+        "GROUP_ID": "123456",
+        "ACCOUNT_ID": "123456"
+    }
+}
+```
+
+## Создание коммита
+
+Сообщения коммитов должны быть хорошо отформатированы, и чтобы сделать их
+«стандартизированным», мы используем
+[Conventional Commits](https://www.conventionalcommits.org/ru).
+
+```sh
+git add .
+git commit
+```
+
+## Отправьте pull request
+
+Отправьте изменения в ваш репозиторий
+
+```sh
+git push origin <name_of_your_new_branch>
+```
+
+Затем откройте [pull request](https://github.com/SevereCloud/vksdk/pulls)
+с веткой:
+
+- `master` если это багфикс
+- `dev-v1.2.3` если это новая фича

+# API
+
+[![PkgGoDev](https://pkg.go.dev/badge/github.com/SevereCloud/vksdk/v2/api)](https://pkg.go.dev/github.com/SevereCloud/vksdk/v2/api)
+[![VK](https://img.shields.io/badge/developers-%234a76a8.svg?logo=VK&logoColor=white)](https://vk.com/dev/first_guide)
+
+Данная библиотека поддерживает версию API **5.122**.
+
+## Запросы
+
+В начале необходимо инициализировать api с помощью [ключа доступа](https://vk.com/dev/access_token):
+
+```go
+vk := api.NewVK("<TOKEN>")
+```
+
+### Запросы к API
+
+- `users.get` -> `vk.UsersGet(api.Params{})`
+- `groups.get` с extended=1 -> `vk.GroupsGetExtended(api.Params{})`
+
+Список всех методов можно найти на
+[данной странице](https://pkg.go.dev/github.com/SevereCloud/vksdk/v2/api?tab=doc#VK).
+
+Пример запроса [`users.get`](https://vk.com/dev/users.get)
+
+```go
+users, err := vk.UsersGet(api.Params{
+	"user_ids": 1,
+})
+if err != nil {
+	log.Fatal(err)
+}
+```
+
+### Параметры
+
+[![PkgGoDev](https://pkg.go.dev/badge/github.com/SevereCloud/vksdk/v2/api/params)](https://pkg.go.dev/github.com/SevereCloud/vksdk/v2/api/params)
+
+Модуль params предназначен для генерации параметров запроса.
+
+```go
+// import "github.com/SevereCloud/vksdk/v2/api/params"
+
+b := params.NewMessageSendBuilder()
+b.PeerID(123)
+b.Random(0)
+b.DontParseLinks(false)
+b.Message("Test message")
+
+res, err = api.MessageSend(b.Params)
+```
+
+### Обработка ошибок
+
+[![VK](https://img.shields.io/badge/developers-%234a76a8.svg?logo=VK&logoColor=white)](https://vk.com/dev/errors)
+
+Обработка ошибок полностью поддерживает методы
+[go 1.13](https://blog.golang.org/go1.13-errors)
+
+```go
+if errors.Is(err, api.ErrAuth) {
+	log.Println("User authorization failed")
+}
+```
+
+```go
+var e *api.Error
+if errors.As(err, &e) {
+	switch e.Code {
+	case api.ErrCaptcha:
+		log.Println("Требуется ввод кода с картинки (Captcha)")
+		log.Printf("sid %s img %s", e.CaptchaSID, e.CaptchaImg)
+	case 1:
+		log.Println("Код ошибки 1")
+	default:
+		log.Printf("Ошибка %d %s", e.Code, e.Text)
+	}
+}
+```
+
+Для Execute существует отдельная ошибка `ExecuteErrors`
+
+### Запрос любого метода
+
+Пример запроса [users.get](https://vk.com/dev/users.get)
+
+```go
+// Определяем структуру, которую вернет API
+var response []object.UsersUser
+var err api.Error
+
+params := api.Params{
+	"user_ids": 1,
+}
+
+// Делаем запрос
+err = vk.RequestUnmarshal("users.get", &response, params)
+if err != nil {
+	log.Fatal(err)
+}
+
+log.Print(response)
+```
+
+### Execute
+
+[![PkgGoDev](https://pkg.go.dev/badge/github.com/SevereCloud/vksdk/v2/errors)](https://pkg.go.dev/github.com/SevereCloud/vksdk/v2/api#VK.Execute)
+[![VK](https://img.shields.io/badge/developers-%234a76a8.svg?logo=VK&logoColor=white)](https://vk.com/dev/execute)
+
+Универсальный метод, который позволяет запускать последовательность других
+методов, сохраняя и фильтруя промежуточные результаты.
+
+```go
+var response struct {
+	Text string `json:"text"`
+}
+
+err = vk.Execute(`return {text: "hello"};`, &response)
+if err != nil {
+	log.Fatal(err)
+}
+
+log.Print(response.Text)
+```
+
+### Обработчик запросов
+
+Обработчик `vk.Handler` должен возвращать структуру ответа от VK API и ошибку.
+В качестве параметров принимать название метода и параметры.
+
+```go
+vk.Handler = func(method string, params ...api.Params) (api.Response, error) {
+	// ...
+}
+```
+
+Это может потребоваться, если вы можете поставить свой обработчик с
+[fasthttp](https://github.com/valyala/fasthttp) и логгером.
+
+Стандартный обработчик использует [encoding/json](https://pkg.go.dev/net/http)
+и [net/http](https://pkg.go.dev/net/http). В стандартном обработчике можно
+настроить ограничитель запросов и HTTP клиент.
+
+#### Ограничитель запросов
+
+К методам API ВКонтакте (за исключением методов из секций secure и ads) с
+ключом доступа пользователя или сервисным ключом доступа можно обращаться не
+чаще 3 раз в секунду. Для ключа доступа сообщества ограничение составляет 20
+запросов в секунду. Если логика Вашего приложения подразумевает вызов
+нескольких методов подряд, имеет смысл обратить внимание на метод execute. Он
+позволяет совершить до 25 обращений к разным методам в рамках одного запроса.
+
+Для методов секции ads действуют собственные ограничения, ознакомиться с ними
+Вы можете на [этой странице](https://vk.com/dev/ads_limits).
+
+Максимальное число обращений к методам секции secure зависит от числа
+пользователей, установивших приложение. Если приложение установило меньше 10
+000 человек, то можно совершать 5 запросов в секунду, до 100 000 — 8 запросов,
+до 1 000 000 — 20 запросов, больше 1 млн. — 35 запросов в секунду.
+
+Если Вы превысите частотное ограничение, сервер вернет ошибку с кодом
+**6: "Too many requests per second."**.
+
+С помощью параметра `vk.Limit` можно установить ограничение на определенное
+количество запросов в секунду
+
+### HTTP client
+
+В модуле реализована возможность изменять HTTP клиент с помощью параметра
+`vk.Client`
+
+Пример прокси
+
+```go
+
+dialer, _ := proxy.SOCKS5("tcp", "127.0.0.1:9050", nil, proxy.Direct)
+httpTransport := &http.Transport{
+	Dial:              dialer.Dial,
+}
+httpTransport.Dial = dialer.Dial
+
+client := &http.Client{
+	Transport: httpTransport,
+}
+
+vk.Client = client
+```
+
+### Ошибка с Captcha
+
+[![VK](https://img.shields.io/badge/developers-%234a76a8.svg?logo=VK&logoColor=white)](https://vk.com/dev/captcha_error)
+
+Если какое-либо действие (например, отправка сообщения) выполняется
+пользователем слишком часто, то запрос к API может возвращать ошибку
+"Captcha needed". При этом пользователю понадобится ввести код с изображения
+и отправить запрос повторно с передачей введенного кода Captcha в параметрах
+запроса.
+
+**Код ошибки**: 14  
+**Текст ошибки**: Captcha needed
+
+Если возникает данная ошибка, то в сообщении об ошибке передаются также
+следующие параметры:
+
+- `err.CaptchaSID` - идентификатор captcha
+- `err.CaptchaImg` - ссылка на изображение, которое нужно показать
+  пользователю, чтобы он ввел текст с этого изображения.
+
+В этом случае следует запросить пользователя ввести текст с изображения
+`err.CaptchaImg` и повторить запрос, добавив в него параметры:
+
+- `captcha_sid` - полученный идентификатор
+- `captcha_key` - текст, который ввел пользователь
+

+# Bots Long Poll API
+
+[![PkgGoDev](https://pkg.go.dev/badge/github.com/SevereCloud/vksdk/v2/longpoll-bot)](https://pkg.go.dev/github.com/SevereCloud/vksdk/v2/longpoll-bot)
+[![VK](https://img.shields.io/badge/developers-%234a76a8.svg?logo=VK&logoColor=white)](https://vk.com/dev/bots_longpoll)
+
+## Подключение Bots Long Poll API
+
+Long Poll настраивается автоматически. Вам не требуется заходить в настройки
+сообщества.
+
+### Версия API
+
+Данная библиотека поддерживает версию API **5.122**.
+
+### Инициализация
+
+Модуль можно использовать с ключом доступа пользователя, полученным в
+Standalone-приложении через Implicit Flow(требуются права доступа: **groups**)
+или с ключом доступа сообщества(требуются права доступа: **manage**).
+
+В начале необходимо инициализировать api:
+
+```go
+vk := api.NewVK("<TOKEN>")
+```
+
+А потом сам longpoll
+
+```go
+lp, err := longpoll.NewLongPoll(vk api.VK, groupID int)
+// По умолчанию Wait = 25
+// lp.Wait = 90
+// lp.Ts = "123"
+```
+
+### HTTP client
+
+В модуле реализована возможность изменять HTTP клиент - `lp.Client`
+
+Пример прокси
+
+```go
+dialer, _ := proxy.SOCKS5("tcp", "127.0.0.1:9050", nil, proxy.Direct)
+httpTransport := &http.Transport{
+	Dial:              dialer.Dial,
+	// DisableKeepAlives: true,
+}
+httpTransport.Dial = dialer.Dial
+lp.Client.Transport = httpTransport
+```
+
+### Обработчик событий
+
+Для каждого события существует отдельный обработчик, который передает функции
+`ctx` и `object`.
+
+Пример для события `message_new`
+
+```go
+lp.MessageNew(func(ctx context.Context, obj events.MessageNewObject) {
+	...
+})
+```
+
+Если вы хотите получать полный ответ от Long Poll(например для сохранения `ts`
+или специальной обработки `failed`), можно воспользоваться следующим обработчиком.
+
+```go
+lp.FullResponse(func(resp object.LongPollBotResponse) {
+	...
+})
+```
+
+Полный список событий Вы найдёте [в документации](https://vk.com/dev/groups_events)
+
+### Контекст
+
+Поля `groupID`, `ts` и `eventID` передаются в `ctx`. Чтобы получить их, можно
+воспользоваться следующими функциями:
+
+```go
+groupID := events.GroupIDFromContext(ctx)
+eventID := events.EventIDFromContext(ctx)
+ts := longpoll.TsFromContext(ctx)
+```
+
+### Запуск и остановка
+
+```go
+// Запуск
+if err := lp.Run(); err != nil {
+	log.Fatal(err)
+}
+
+// Безопасное завершение
+// Ждет пока соединение закроется и события обработаются
+lp.Shutdown()
+
+// Закрыть соединение
+// Требует lp.Client.Transport = &http.Transport{DisableKeepAlives: true}
+lp.Client.CloseIdleConnections()
+```
+
+## Пример
+
+```go
+package main
+
+import (
+	"log"
+
+	"github.com/SevereCloud/vksdk/v2/api"
+
+	longpoll "github.com/SevereCloud/vksdk/v2/longpoll-bot"
+	"github.com/SevereCloud/vksdk/v2/events"
+)
+
+func main() {
+	vk := api.NewVK("<TOKEN>")
+	lp, err := longpoll.NewLongPoll(vk, 12345678)
+	if err != nil {
+		panic(err)
+	}
+
+	lp.MessageNew(func(ctx context.Context, obj events.MessageNewObject) {
+		log.Print(obj.Message.Text)
+	})
+
+	lp.Run()
+}
+
+```
