+# LINE Messaging API SDK for Rust
+## Introduction
+The LINE Messaging API SDK for Rust makes it easy to develop bots using LINE Messaging API, and you can create a sample bot within minutes.
+## Documentation
+See the official API documentation for more information.
+- English: <https://developers.line.biz/en/docs/messaging-api/overview/>
+- Japanese: <https://developers.line.biz/ja/docs/messaging-api/overview/>
+## Requirements
+This library requires Rust nightly.
+## Installation
+```
+[dependencies]
+line-bot-sdk-rust = "0.1"
+```
+If you use `rocket support`.
+```
+[dependencies]
+line-bot-sdk-rust = { version = "0.1", features = ["rocket_support"] }
+```
+## Configuration
+```
+extern crate line_bot_sdk_rust as line;
+use line::bot::LineBot;
+
+fn main() {
+    let bot = LineBot::new("<channel secret>", "<channel access token>");
+}
+```
+## How to use
+The LINE Messaging API uses the JSON data format.
+ parse_event_request() will help you to parse the HttpRequest content and return a Result<[Events](`events::Events`) , &'static str> Object.
+ ```
+ let result: Result<Events, &'static str> =
+     bot.parse_event_request(signature, body);
+ ```
+
+ ```
+ match result {
+     Ok(events) => {
+         for event in events.events {
+             ...
+         }
+     }
+     Err(msg) => {}
+ }
+ ```
