+# OpenWebUI Bot for Channels Integration
+
+This project integrates the [Open WebUI bot](https://github.com/open-webui/bot) to provide AI responses in OpenWebUI channels.
+
+## Overview
+
+The OpenWebUI bot connects to your OpenWebUI instance via WebSocket and listens for messages in channels. When a message mentions the AI (using trigger words like `@ai`), the bot processes the message and sends a response back to the channel.
+
+## Running the Bot Locally
+
+To run the bot locally:
+
+1. Make sure you have Python 3.7+ installed
+2. Install the required dependencies:
+   ```bash
+   pip install python-socketio aiohttp python-dotenv
+   ```
+3. Configure the bot by creating a `.env` file in the `openwebui-bot` directory:
+   ```
+   WEBUI_URL=http://104.225.217.215:8080
+   TOKEN=GdCU4ieYDqHsLfH2
+   MODEL_ID=llama3.1
+   ```
+4. Run the bot:
+   ```bash
+   python run_openwebui_bot.py
+   ```
+
+## Deploying the Bot on the Server
+
+To deploy the bot on your server:
+
+1. Run the deployment script:
+   ```bash
+   ./deploy_bot.sh
+   ```
+2. Follow the instructions provided by the script to copy the deployment package to your server and run the deployment.
+
+## Bot Configuration
+
+The bot is configured using environment variables in the `.env` file:
+
+- `WEBUI_URL`: URL of your OpenWebUI instance (e.g., `http://104.225.217.215:8080`)
+- `TOKEN`: API key for authentication
+- `MODEL_ID`: ID of the model to use (e.g., `llama3.1`)
+
+Additional configuration options can be added to the `.env` file:
+
+```
+SYSTEM_PROMPT="You are a helpful AI assistant."
+TEMPERATURE=0.7
+MAX_TOKENS=2048
+TOP_P=0.9
+TRIGGERS=@ai,@bot,@assistant,@chatbot
+RESPOND_TO_ALL=false
+```
+
+## Using the Bot
+
+Once the bot is running, you can use it in OpenWebUI channels:
+
+1. Create a channel in OpenWebUI
+2. Send a message that mentions the bot (e.g., `@ai What is the capital of France?`)
+3. The bot will process your message and send a response
+
+## Troubleshooting
+
+If the bot is not responding to messages:
+
+1. Check that the bot is running and connected to OpenWebUI
+2. Verify that you're using one of the trigger words (e.g., `@ai`)
+3. Check the logs for any errors
+4. Make sure your OpenWebUI URL and API key are correct
+
+## Logs
+
+The bot logs to both the console and a file named `bot_debug.log`. You can check this file for detailed information about what the bot is doing and any errors it encounters.
