+You can also configure your fixers from vimrc using `g:ale_fixers`, before or
+after ALE has been loaded. A `*` in place of the filetype will apply the
+corresponding list of fixers to all filetypes. If a subsequent specific filetype
+match is found it will be used instead of `*`. Note that using a plain list for
+`g:ale_fixers` is not supported.
 
 ```vim
 " In ~/.vim/vimrc, or somewhere similar.
 let g:ale_fixers = {
+\   '*': ['remove_trailing_lines', 'trim_whitespace'],
 \   'javascript': ['eslint'],
 \}
 ```
