IMPORTANT: Any data or custom CSS added to Customiser > Additional CSS will not be lost when updating your theme. However, if you have made change to the core theme files, updating your theme WILL override your customisations.
If you need to customise the core files, make sure to use the child theme that comes with the ThemeForest download. You'll find the child theme in the folder Child_theme.
A child theme is installed in the same way as the parent theme. Refer to this section about theme installation. Once you have uploaded your child theme make sure to activate it. You can then add any custom CSS to the style.css file that comes with the child theme.
