+## Environment Setup
+
+This repository uses a `.env` file for configuration, including GitHub authentication.
+
+### Loading Environment Variables
+
+To load environment variables from `.env`:
+
+```bash
+source load_env.sh
+```
+
+This will export `GITHUB_TOKEN` and other variables from `.env` to your current shell session.
+
+### Using GITHUB_TOKEN
+
+The `GITHUB_TOKEN` can be used for:
+
+1. **GitHub API calls**: Export it and use in scripts or API requests
+   ```bash
+   source load_env.sh
+   curl -H "Authorization: token $GITHUB_TOKEN" https://api.github.com/user
+   ```
+
+2. **Git HTTPS authentication** (if needed): Configure git to use the token:
+   ```bash
+   git config credential.helper "$(pwd)/git-credential-helper.sh"
+   ```
+
+**Note**: This repository is currently configured to use SSH authentication (recommended). The token is available for other GitHub API operations if needed.
