-A Github action plugin to send notification to telegram 
+# GitHub Action: Telegram Event Notifier
+
+This GitHub Action sends GitHub events as messages to a Telegram chat or channel or group or a specific topic in a group or thread.
+
+## Usage
+
+To use this GitHub Action, you need to have a Telegram bot token and a chat ID.
+
+1. Create a new Telegram bot by talking to the [BotFather](https://t.me/BotFather) on Telegram and follow the instructions to obtain the bot token.
+
+2. Find out the chat ID where you want to receive the event messages. You can use the [getUpdates](https://core.telegram.org/bots/api#getupdates) API method or search for the bot username in the Telegram app to get the chat ID.
+
+3. In your GitHub repository, create a new workflow file (e.g., `.github/workflows/telegram-event-notifier.yml`) and define the following:
+
+   ```yaml
+   name: Telegram Gate
+
+   on:
+     issue_comment:
+       types: created
+     issues:
+       types: [opened, edited, pinned, closed, reopened, assigned, labeled]
+     pull_request:
+       types:
+         [opened, closed, edited, ready_for_review, review_requested, reopened]
+     pull_request_review_comment:
+       types: created
+     push:
+
+     jobs:
+       build:
