How to add another page in appearance tab of admin panel?

Currently I am working on WordPress and I want to know can I add 1 more page in admin panel appearance menu so that it looks like this: ?

Appearance
  Themes
  Widgets
  Menus
  Editor

I want to add one more page after Editor like “Theme option”.

You’d use the add_theme_page() function. Basically, it’s the same as adding any other settings page, but instead of add_options_page(), you use add_theme_page().
