Why you should use Child Theme
If you plan to edit theme files, then it would be good idea to use for this purpose child theme. This way, when you will update main theme, you will not lose your modifications.

Be aware that using child theme is not bulletproof method. For example if main theme will change drastically in same part that you have edited via Child theme, then your site might not work proper. However this is rare situation, but is good habit to review your child theme changes after main theme update.
