 ## Options
 
+This module tries to be very flexible with it's configuration option. For many options you can define either a boolean, a string, a 
+regular expression or an array with a mixture of string and regular expressions. If a boolean is passed in the option is simply set 
+to true or false for all files. If the option is a string the filename is searched for this substring. If the option is regular
+expression it is tested against each file, and finally if the option is an array the test is executed against every element of the
+array and accepted if any of the elements returns true with the previous rules defined. You could even nest arrays if you wanted to.
+
+An example:
+```
+options.ignoreTokens = [ 'de_DE', /en_*/ ]
+// => matches any english language as well the German translation for Germany
+```
