+Within an Enhance application, first add a `styleguide.json` JSON config file (or choose another name) at the root of your Enhance project. You can copy [the default configuration](https://github.com/enhance-dev/enhance-styles/blob/main/config.json) to get started. See individual sections below for more information on configuring these options.
+
+Next, edit your project’s `.arc` file to tell Enhance Styles where to find this config file by including the following:
+
+```arc
+@enhance-styles
+config styleguide.json

 ## Prior art
 
 Enhance styles would not exist without the breakthrough thinking of [Adam Morse](https://mrmrs.cc/) who realized that creating a capped size stylesheet with common, single use, low specificity classes results in better performance and maintanance than append only stylesheets that can only grow as more features are added. His CSS work can be seen in [Tachyons](https://tachyons.io/).
