I often see people struggling to customize the theme they're using, very much unaware of the option to download the themes or why this is needed.
Would be nice to have a dashboard that helps to download the theme for their current version and unzip it in the right place. Additionally it should have some documentation explaining that they should add the files to source control and (if needed) to their csproj to make sure it deploys.
Maybe this dashboard needs to be only available when the site is not in the runtime mode Production.
