 Simplest webpack loader for https://github.com/Quramy/typed-css-modules
-Has no configuration atm.

+I suggest using it as preloader. Unless you change the options (see below), it
+will generate `.css.d.ts` files near the `.css`. Please take a look at
+[this discussion](https://github.com/Quramy/typed-css-modules/issues/2) to make a decision.
+
+You can affect how `typed-css-modules` behaves by using query parameters. The loader
+will pass on any query parameters you send give it to the constructor of the DtsCreator
+class. For more info on available options, have a look at the
+[DtsCreator constructor](https://github.com/Quramy/typed-css-modules#new-dtscreatoroption).
