The Main Menu allows the user to interact with Ardour and may appear daunting at first. Below is a reference of all the menus and submenus.
Most of these menus, and probably all of the most used ones, have keyboard shortcuts to make using them easier and faster. A summary of these shortcuts can be found on the Defaults Keyboard Bindings page, and every menu in Ardour can be reassigned to an user defined key binding, or used via OSC with a control surface.
Some menu items placement may depend on the OS, e.g. the "About" window may not be in the Help menu on Mac systems.
