 " Customization:
 "
-" There are two optional sets of highlighting:
+" To use the old highlighting style, add this to your .vimrc:
 "
-" 1. The BIFs (built-in functions) are highlighted by default. To disable
-"    this, put the following line in your vimrc:
+"     let g:erlang_old_style_highlight = 1
 "
-"      let g:erlang_highlight_bifs = 0
+" To highlight further module attributes, add them to
+" ~/.vim/after/syntax/erlang.vim:
 "
-" 2. To enable highlighting some special atoms, put this in your vimrc:
