+the source archive. The LilyPond file type is detected if your file
+@file{~/.vim/filetype.vim} has the following content:
+@example
+ if exists("did_load_filetypes")
+ finish
+ endif
+ augroup filetypedetect
+ au! BufNewFile,BufRead *.ly setf lilypond
+ augroup END
+@end example
+In addition, LilyPond's vim-mode files which are installed to
+@file{/usr/share/lilypond/vim/} have to be placed in a path specified
+in your @code{$VIMRUNTIME} environment variable. You can add this path
+to @code{$VIMRUNTIME} by appending the following line to your
+@file{~/.vimrc}:
+@example
+ set runtimepath+=/usr/share/lilypond/vim/
