+
+  With this variable we are able to pass extra arguments for shellcheck
+  for shellcheck invocation.
+
+  For example, if we want shellcheck to follow external sources (`see SC1091`)
+  we can set the variable as such:
+
+  let g:ale_sh_shellcheck_options = '-x'
+
+
 g:ale_linters_sh_shellcheck_exclusions *g:ale_linters_sh_shellcheck_exclusions*
 
   Type: |String|
   Default: `''`
 
   Set this variable to exclude test(s) for shellcheck (-e/--exclude option).
+  To exclude more than one option, separate them with commas.
