Before making any changes, create a backup of your entire website. This ensures that you can revert to a previous state if something goes wrong during the editing process.

### Child Theme Creation:
To preserve your modifications through theme updates, consider creating a child theme. This ensures that your customizations remain intact even when the main theme is updated.

### Understand the Theme Structure:
Familiarize yourself with the structure of your theme. Know where the main files are located, such as header.php, footer.php, style.css, etc. This understanding will help you navigate and make targeted changes.
