Pro Tip: Always read theme reviews and check demo versions to make sure it meets your design and performance expectations.
Step 2: Backup Your Magento Store
Installing a new theme can affect your store’s core files and functionality. It’s crucial to create a full backup of your site files and database using your hosting provider’s control panel or Magento CLI tools. This ensures you can restore your site if anything goes wrong.
Step 3: Upload Theme Files

Option 1: Using Composer (Preferred for Premium Themes)
