+### Setting Up Your Local Environment for Contribution
+
+To ensure that your contributions include your name in the `last_update` section of documentation files automatically, follow these steps to set up your local environment:
+
+#### Creating a `.env` File
+
+1. At the root of your local repository clone, create a file named `.env`.
+2. Inside the `.env` file, add the following line, replacing `"Your Name"` with your actual name:
+
+```sh
+AUTHOR_NAME="Your Name"
+```
+
+3. Save and close the `.env` file. This file will be used by the pre-commit hook to automatically insert your name into the `last_update` section of Markdown files.
+
+#### Installing the Pre-commit Package
+
+The pre-commit package is used to run scripts before each commit automatically, allowing us to update the documentation's `last_update` section seamlessly.
+
+1. Install pre-commit on your system. If you're using pip (Python's package manager), you can install it by running:
+
+```bash
+pip install pre-commit
+```
+
+2. Make sure the update_last_update.sh script is present in the scripts/ directory at the root of your repository and is executable. You may need to run chmod +x scripts/update_last_update.sh to make it executable.
+
+3. Run following command to set up the hook.
+```bash
+pre-commit install
+```
+
+With these steps completed, your local environment is set up to automatically update the last_update section of Markdown files with your name and the current date whenever you make a commit. This process helps maintain accurate documentation and attribution for contributions.
