# Built-In Prototypes

Tinderbox offers a small number of specimen prototypes built into the application that you can added to any Tinderbox document.

- select the Built-In Prototypes submenu of the File menu.
- choose a prototype to add.
- the selected item is added to a 'Prototypes' container in the current document.

If Tinderbox detects an existing 'Prototypes' note (case-sensitive), the newly added prototypes note is added to that container. Otherwise a new 'Prototypes' container is created at root level in the current document.
