+---
+
+To make use of the built-in icons, styles, and plugins in omorphia, you will need to update the config files.
+
+## SvelteKit 
+
+Add the following parts to your `svelte.config.js` file:
+
+```js
+import { preprocess, plugins } from 'omorphia/config/svelte.config'
+
+/** @type {import('@sveltejs/kit').Config} */
+const config = {
+    preprocess: [
+        preprocess,
+    ],
+
+    kit: {
+        vite: {
+            plugins: [
+                ...plugins,
+            ],
+        },
+    },
+};
+
+export default config;
+```
+
+## PostCSS
+
+Create a `postcss.config.cjs` file in the root of your project.
+
+Add the following line to that file:
+
+```js
+module.exports = require('omorphia/config/postcss.config.cjs')
+```
