 A few of Vim's standard `colorschemes` are configured by default, but
 you'll want to override them with your own, like this:

 Without GUI-based Vim, console-based emulation is trickier, as there's no
 easy way to create generous left and right margins. You can approximate it
 by switching from soft-wrap to hard line breaks with `vim-writer` and using
 with a narrow `textwidth`:

-    autocmd FileType markdown set foldcolumn=12 textwidth=74
-    ```

+autocmd FileType markdown set foldcolumn=12 textwidth=74
