Hi, I just purchased Sydney Pro. As a newbie to Wordpress, do I just follow the same installation documentation for ‘Sydney’ for ‘Sydney Pro’? Including setting up a 'Child Theme"? If not, where do I look for installation instructions for Sydney Pro?
Thank you

Yes, just follow the this documentation. That works for the Pro version as well. Once you’ve activated the Pro version, you must activate the theme’s license key through Dashboard > Appearance > Theme License
