In Admin, when you go to Design > Themes, there is box with "Theme Information" title. It is showing Name, Directory, Layouts, Styles and Developer for the theme as attached. How to add or change the developer name in Theme Information.
Please change in theme file manifest.json
#file
design/themes/[THEME_NAME]/manifest.json
#content
{ ... "developer": "Hungryweb", ... }
Thank you very much. I updated the developer. It is done.
