+## Configure your developement environnement
+1. Install necessary packages: run the following command to install the required packages:
+   ```sh
+   pip install langchain psycopg2 python-dotenv scaleway
+   ```
+2. Configure your environnement variables: create a .env file and add the following variables. These will store your API keys, database connection details, and other configuration values.
+   ```sh
+  # .env file
+
+  # Scaleway API credentials
+  SCW_ACCESS_KEY=your_scaleway_access_key
