   This variable can be changed to modify flags given to hdevtools.
 
+  The hdevtools documentation recommends setting GHC options for `hdevtools`
+  with `g:hdevtools_options`. ALE will use the value of `g:hdevtools_options`
+  for the value of `g:ale_haskell_hdevtools_options` by default, so this
+  option can be respected and overridden specifically for ALE.
