+r"""
+This script is used to spam transactions on the Taiko network. It reads the private key and recipient address from a .env file,
+connects to the Taiko network, and sends a specified number of transactions to the recipient address.
+
+Setup:
+1. Create a virtual environment:
+   python -m venv venv
+
+2. Activate the virtual environment:
+   - On Windows: venv\Scripts\activate
+   - On macOS/Linux: source venv/bin/activate
+
+3. Install the required dependencies:
+   pip install -r requirements.txt
+
+4. Create a .env file in the tools/tx_spammer directory with the following content:
+   PRIVATE_KEY=<your_private_key>
+   RECIPIENT_ADDRESS=<recipient_address>
+
+5. Run the script:
+   python tx_spammer.py [--count COUNT] [--amount AMOUNT]
+
+CLI Parameters:
+--count: Number of transactions to send (default: 1)
+--amount: Amount of ETH to send per transaction (default: 0.006)
