When the game application starts up, this is the first page that you see.

The title and description on the left are, as are many of the English entries, best guesses from Google Translate.

On the right are three links to other pages in the Main UI. They are:

Enter the Clubhouse where you choose the set of rules to use for this game,
Registered member where you can sign up or sign in online to the game's clubhouse,
Bird Kind ranking list which is the high score list.

The green circle at the bottom right toggles among three sound settings, Sound & Music, Quiet, Voices Only. Voices Only is displayed here.
