## Overview

This is a small Telegram notification bot. A user sends a command through Telegram; the bot polls for updates and handles `/start`, `/status`, `/test`, and `/help`. The test handler calls the notifier, which sends a message to the configured chat. Configuration is loaded from environment variables, with `python-dotenv` also loading a local `.env` file. The source excerpts show command and notification behavior; no broader automation workflow is evidenced.

Main entry points: [`bot.py`](https://github.com/evoitsykhiv/telegram-notification-bot/blob/main/bot.py) (Command handlers), [`notifier.py`](https://github.com/evoitsykhiv/telegram-notification-bot/blob/main/notifier.py) (Notification sender), [`config.py`](https://github.com/evoitsykhiv/telegram-notification-bot/blob/main/config.py) (Environment config)
