+
+## Requirements
+
+Ensure you have Python 3.x installed. Then, install the necessary packages:
+
+```{bash}
+pip install -r requirements-mysql.txt
+```
+
+Download your vocabulary CSV files from the [Athena website](http://athena.ohdsi.org/vocabulary/list) and place them in a directory of your choice, e.g., `./vocab`. The script will read the files from this directory.
+
+## Instructions
+
+1. **Set Up Environment Variables**:
+   Create a `.env-mysql` file in the same directory as the script. This file should have the following structure:
+
+   ```{bash}
+   SERVER=your_server
+   PORT=your_port
+   USERNAME=your_username
+   PASSWORD=your_password
+   DATABASE=your_database_name
+   VOCAB_FILE_DIR=path_to_your_csv_files
+   DELETE_TABLES=True|False (default True)
+   CREATE_TABLES=True|False (default False)
+   ```
+
+   Replace the placeholders with your actual details.
+
+2. **Run the Script**:
+   Navigate to the script's directory and execute:
+
+   ```{bash}
+   python load_mysql.py
+   ```
+
+3. **Monitor the Output**:
+   The script provides status updates and error messages in the console. It will notify you of the start time, processed lines, remaining lines, and end time for each file.
