"content": "# GUIDE TO INSTALL AND RUN VENOM BOT \n## Venom WhatsApp Bot Installation Guide\n\nThis guide outlines the basic steps to install and run the Venom WhatsApp bot on a Linux server (e.g., a VPS).\n\n## Prerequisites\n\n* A Linux server (Ubuntu 20.04+ recommended)\n* Node.js (v16 or higher) and npm installed\n* PM2 (Process Manager 2) for keeping the bot running in the background\n* Basic command-line knowledge\n\n## Step-by-Step Installation\n\n1. **Connect to your server via SSH:**\n ```bash\n ssh your_username@your_server_ip\n ```\n\n2. **Install Node.js and npm (if not already installed):**\n ```bash\n sudo apt update\n sudo apt install -y nodejs npm\n ```\n *Verify installation:*\n ```bash\n node -v\n npm -v\n ```\n\n3. **Install PM2:**\n ```bash\n sudo npm install -g pm2\n ```\n\n4. **Create a dedicated user for the bot (recommended for security):**\n ```bash\n sudo adduser whatsappbot\n sudo usermod -aG sudo whatsappbot # Grant sudo access temporarily if needed for setup\n su - whatsappbot\n ```\n *(You will be prompted to set a password for the new user)*\n\n5. **Clone the Venom Bot repository (or your custom bot code):**\n ```bash\n git clone https://github.com/orkestral/venom-bot.git /home/whatsappbot/venom-whatsapp-bot\n # Or, if you have your custom bot code:\n # git clone your_bot_repo_url /home/whatsappbot/venom-whatsapp-bot\n cd /home/whatsappbot/venom-whatsapp-bot\n ```\n\n6. **Install dependencies:**\n ```bash\n npm install\n ```\n\n7. **Configure your bot (e.g., `config.js` or `.env` file ):**\n * Create a `.env` file in your bot's root directory (`/home/whatsappbot/venom-whatsapp-bot/.env`).\n * Add necessary environment variables, such as `N8N_WEBHOOK_URL` (the URL of your n8n webhook), `API_SECRET_KEY`, `BOT_SESSION_NAME`, etc.\n Example `.env` content:\n ```\n N8N_WEBHOOK_URL=https://your-n8n-instance.com/webhook/whatsapp-incoming\n API_SECRET_KEY=1234567890\n BOT_SESSION_NAME=venom-whatsapp-bot\n PORT=3000\n ```\n\n8. **Start the bot with PM2:**\n ```bash\n pm2 start index.js --name venom-whatsapp-bot\n # If your main bot file is named differently (e.g., bot.js ):\n # pm2 start bot.js --name venom-whatsapp-bot\n ```\n\n9. **Save PM2 process list (to restart on server reboot):**\n ```bash\n pm2 save\n pm2 startup\n ```\n *Follow the instructions provided by `pm2 startup` to enable auto-start.*\n\n10. **Link WhatsApp:**\n * When you start the bot for the first time, it will generate a QR code in the terminal.\n * Scan this QR code with your WhatsApp mobile app (WhatsApp Settings -> Linked Devices -> Link a Device).\n\n## Common PM2 Commands\n\n* `pm2 list`: List all running PM2 processes\n* `pm2 logs venom-whatsapp-bot`: View logs for your bot\n* `pm2 restart venom-whatsapp-bot`: Restart your bot\n* `pm2 stop venom-whatsapp-bot`: Stop your bot\n* `pm2 delete venom-whatsapp-bot`: Remove your bot from PM2\n\nRemember to replace placeholder values like `your_username`, `your_server_ip`, `your_bot_repo_url`, and `your-n8n-instance.com` with your actual details."
