 The current supported options are:
 
 + `files` (string[]): An array of test files to include. Globs are supported.
+  Note: any glob that starts with a `!` (bang character) will be treated as
+  an ignore glob, e.g. `'!test/**/node_modules/**/*'` will ignore all files
+  in nested `node_modules` directories that would otherwise be matched.
 + `reporters` (string[]): An array of reporters to use. May be relative path
 strings, or module name strings.
