+### 5.iv. How can I change or disable the highlights ALE uses?
+
+ALE's highlights problems with highlight groups which link to `SpellBad`,
+`SpellCap`, `error`, and `todo` groups by default. The characters that are
+highlighted depend on the linters being used, and the information provided to
+ALE.
+
+Highlighting can be disabled completely by setting `g:ale_set_highlights` to
+`0`.
+
+```vim
+" Set this in your vimrc file to disabling highlighting
+let g:ale_set_highlights = 0
+```
+
+You can control all of the highlights ALE uses, say if you are using a different
+color scheme which produces ugly highlights. See `:help ale-highlights` for more
+information.
