+# Overview
+
+**Telegram Bot** is a basic, informative Telegram bot that interacts with users via simple commands. It's built using the [node-telegram-bot-api](https://github.com/yagop/node-telegram-bot-api) library.
+
+## Features
+
+- `/start` - Sends a welcome message when interacting with the bot.
+- `/help` - Lists all available commands for the user.
+- `/info` - Provides information about the bot.
+- `/joke` - Fetches a random joke from an external joke API and sends it to the user.
+- Echoes any non-command text sent to the bot.
+
+## Installation
+
+1. Clone this repository:
+
+   ```bash
+   git clone https://github.com/Jesewe/telegram-bot.git
+   cd telegram-bot
+   ```
+
+2. Install the required dependencies:
+
+   ```bash
+   npm install
+   ```
+
+3. Create a `config.json` file in the root directory with the following structure:
+
+   ```json
+   {
+     "token": "YOUR_REAL_BOT_TOKEN_HERE",
+     "botName": "Telegram Bot"
+   }
+   ```
+
+4. Run the bot:
+
+   ```bash
+   node bot.js
+   ```
+
+## Dependencies
+
+- **[node-telegram-bot-api](https://github.com/yagop/node-telegram-bot-api)**: Telegram Bot API wrapper for Node.js.
+- **[axios](https://axios-http.com/)**: HTTP client for making requests to the external joke API.
+
+## Logging
+
+When the bot starts, it will log the following to the console:
+
+```bash
+Telegram Bot is running...
+```
+
+Any polling errors or issues fetching the joke will also be logged in the console with error details. For example:
+
+```bash
+Error fetching joke: Error message here
+```
