Update Rouge
Get the newest version of Rouge without losing your settings.
When a new version of Rouge is out, Shopify shows an Update available message on the theme in Online Store › Themes.
Select Update available, then Add to theme library. Shopify makes a copy of your theme on the new version, with your settings and content carried over.
Open the copy in the theme editor and check the pages you use most.
Publish the copy when it looks right. Your old version stays in the theme library in case you need it.
Edited the theme code?
Changes made in Edit code are not carried over to the new version. Keep a list of them so you can add them again.
Which version am I on?
Open Theme settings › Theme info. The version number is the one to share with us when you ask for help.
