Okay so maybe you want to add a copyright in the footer or something else. Currently your not able to do this in the mobile app, so you’ll have to again use Puffin or something to get desktop view, or just actually use a desktop haha.
This is actually pretty simple it’s just a one field view once you are logged in.
Navigate to settings (設定) then basic settings (基本設定).
Under サイト名／説明 you’ll see three separate boxes.
Top- Site Title
Middle - Site Description
Obviously you’re looking to modify the footer so write whatever you’d like to be in the footer of each page, and then hit save on the top right! Your done. The changes should take effect on your website immediately.
