Interface
Like vi, Vim's interface is based not on menus or icons but on commands given in a text user interface; its GUI mode, gVim, adds menus and toolbars for commonly used commands but the full functionality is still expressed through its command line mode.
Vim has a built-in tutorial for beginners (accessible through the "vimtutor" command). There is also the Vim Users' Manual that details Vim's features. This manual can be read from within Vim, or found online.
Vim also has a built-in help facility (using the :help command) that allows users to query and navigate through commands and features.
